Comparing Seidel’s Natural Double Shot and Horween’s Natural Chromexcel
Watch on YouTubeVideo summary
The video explores the nuanced differences between Horween's Natural Chromexcel and Seidel's Natural Double Shot, two highly regarded heritage boot leathers often debated by enthusiasts. To ensure a fair comparison free from color bias or batch variations, the host selected pairs of boots purchased within months of each other that had accumulated similar amounts of wear: an Oak Street Bootmakers trench boot in Horween leather and a Parkhurst Richmond brogue in Seidel's "light natural" Double Shot. While both leathers share a foundational history rooted in industrial applications for engine gaskets, their production timelines differ significantly; Chromexcel has been refined since the 1920s through an extensive eighty-nine-step process over twenty-eight days, whereas Double Shot was recently redeveloped and reintroduced to modern markets around 2020. Despite these historical divergences, both tanneries utilize a similar core methodology involving chrome tanning followed by vegetable retannage, though the finishing stages differ in how they apply oils and waxes to achieve their distinct characteristics.
Upon tactile examination, the two leathers present contrasting sensory profiles that influence their performance and aging behavior. Natural Chromexcel feels wetter and oilier out of the box, with a pliable temper that allows it to mold quickly to the foot for immediate comfort but which can lead to significant stretching over time if not monitored closely. In contrast, Double Shot possesses a firmer structure due to its waxy composition, offering more support and resisting deformation around areas like the ankle shafts. This structural difference also affects how scratches are handled; while Chromexcel shows scuffs easily that can be smoothed out with vigorous rubbing and thumb heat thanks to its oily nature, Double Shot hides minor abrasions better but requires conditioning treatments rather than simple friction to remove deeper marks or restore shine after wear.
The aesthetic evolution of these leathers over time reveals further distinctions in how they interact with light, UV exposure, and patina development. Both boots started as pale honey tones but darkened differently during the Australian summer; Chromexcel exhibited a dramatic, uneven darkening that created high-contrast creases and rich golden caramel hues quickly, while Double Shot faded more evenly into a consistent tone without developing deep shadows in the fold lines. Additionally, Chromexcel demonstrated superior pull-up effects when stressed or folded due to its oil content oxidizing faster, whereas the waxy barrier of Double Shot provided better protection against moisture but resulted in a subtler sheen that gleams less intensely after brushing compared to the oily finish of Horween's leather. Ultimately, while both materials are comparable in quality and care requirements involving Neatsfoot oil and Venetian Shoe Cream, they serve slightly different preferences depending on whether one prioritizes rapid patina storytelling or long-term structural integrity with a cleaner appearance.

I've seen forums debate which one is
better.
Uh Horween's Chromexcel or Seidel's
Double Shot.
Well, getting any argument about the
color out of the way, let's compare
natural Chromexcel with natural Double
Shot.
>> [music]
[music]
>> Good day. Welcome back to Bootlosophy,
my channel about heritage boots. And if
this is your first time, my name is
Tack.
I'm on Wadjuk country here in Gallop in
Wadjuk Nyoongar Boodja.
I was recently asked by a viewer what
the difference was between Horween's
Chromexcel and Seidel's Double Shot.
Apart from the cheeky reply that one was
made by Horween and the other by Seidel,
>> [laughter]
>> I was intrigued and so I set off to
research the difference. Firstly, uh in
as much as the tanning processes
differed, uh as well as what people
thought of them, and also how I find the
two leathers.
But first, in order to remove any, you
know, taint by comparing different
colors, because I have seen comments
that, you know, one is more prone to tea
core than the other, uh so leaving the
color out, I decided to compare the two
versions of natural.
Uh Horween's natural Chromexcel and
Seidel's natural Double Shot.
And to do that,
I decided to touch and feel and tell you
how uh these two boots wore. Uh these
boots being bought no more than 3 months
apart in 2021, and both having about the
same amount of wear.
So, this is the Parkhurst Richmond in
the old 602 last in Seidel's light
natural Double Shot.
And this is uh Oak Street Bootmakers
Trench Boot in Horween's natural
Chromexcel.
Taking each in turn, I bought this Oak
Street Bootmakers trench boot in
November of 2021 in their classic toe
capped natural Chromexcel with an oil
infused leather sole.
I have done a review of it and to my
mind, Oak Street is one of the most
underrated bootmakers out there
producing really good stuff in good
solid service boot designs, particularly
when they go on sale.
Apart from my usual, you know, four-week
break-in period where I wore these
exclusively for a week and then every
other day for a second week and then
took a couple of weeks where I wore them
every three or four days.
I have put these on about once a month
since then.
>> [snorts]
>> They're
easy to reach for because they're made
over a comfortable reasonably round toe
last and the leather sole construction
is both flexible and comfortable.
In my review, I noted that the clicking
was excellent and perhaps the brand's
owner George was simply able to walk
over to
Chicago neighbor Horween and select some
great hides directly from the factory.
But it then and still now has not shown
too much loose grain or, you know, even
wrinkles worth talking about
particularly on the vamp.
And the interesting thing is that while
it darkened to a what would you call
this a mellow honey in use,
I have a Parkhurst brogue model
called the Spalding which I bought four
months earlier and this is a natural
Chromexcel that's just darkened to the
color of milk chocolate.
And there's no way I've worn these any
more than that trench boot.
But I'm going to compare it
to this Parkhurst.
The cap toe model called the Richmond in
Sidol's double shot.
When Parkhurst released it, they called
it the light natural double shot, but
since then I've come to understand that
the word light merely denoted the
natural color and there really isn't a
dark natural
uh a shot.
This is made when Parkhurst was still
partnered with its uh Batavia, New York
factory before COVID closed that
factory.
I bought it in February of 2022 and
obviously was made a few months before
that.
In all honesty, while I have my fair
share of Parkhurst plain toe Allen boot,
their Richmond is my favorite design
because I think that toe cap gives it a
more like a complete service boot
aesthetic.
This pair was my first pair in saddle
leather put on top of a grippy uh low
profile uh day night sole
and it has the combination 602 last
where it's narrow in the heel and the
waist and comfortably wide in the ball
of the foot. This is another easy to
reach for boot, especially in this now
mellowed color.
And so I've worn it about the same
number of times as the Oak Street uh
trench boot.
You can also check out the review I did
and I'm going to put links to both
websites below, but note that while uh
Oak Street still makes this trench boot,
Parkhurst have evolved their production
methods and in particular the 602 last
as well.
First, let's take a look at how Horween
produces Chromexcel.
Horween is a famous tannery located in
Chicago uh started in 1905 and is still
run by the Horween family.
In the early 1910s, Horween developed
Chromexcel.
And the story goes that it was first
developed for an industrial purpose,
specifically to be used as seals and
gaskets for engines. Apparently, rubber
gaskets failed catastrophically, whereas
leather gaskets failed by degrees and
they say that experienced mechanics
could hear the engine gasket start to
perish.
Uh the tanning of Chromexcel takes four
stages. First, the hide is chrome tanned
with chromium salts that preserve the
leather and then gives it a flexible
base.
Then it's re-tanned using vegetable
extracts to make it more durable and
give it a richer structure and
aesthetic.
Then the third step is hot stuffing,
where the hides are placed in heated
drums and stuffed with a secret mixture
of animal oils, greases, and waxes.
This uh pumps the fibers full of oils
and waxes and gives it an an oily feel
and a really intense pull-up effect when
stressed or folded.
Uh Finally, the hide is then aniline
dyed and dried, then hand brushed and
rubbed with oils and conditioners.
In its natural state, of course, no dyes
go on.
Uh this process famously takes 89
individual steps over 28 days and takes
the hide through all the floors of the
Horween factory.
Seidel, on the other hand, is said to
have developed double shot in 2020.
Seidel was founded in 1945 in Milwaukee,
Wisconsin. Uh it's all still in family
hands.
Apparently, Seidel redeveloped a similar
tannage to this, which they originally
developed in the 1940s.
>> [snorts]
>> In 2020, Seidel collaborated with a few
uh Pacific Northwest bootmakers to
redevelop this leather.
There are rumors, but not that I could
find a fact-checkable fact, that it was
developed in response to Horween being
unable to produce the volume of
Chromexcel required by PNW brands during
the COVID years.
Uh it follows a similar process to
Chromexcel. The hide is first chrome
tanned and then re-tanned with vegetable
extracts that gives it that structural
firmness and a rich aging capability.
From what I can gather, the double shot
process differs from Chromexcel's in
that the re-tanned hides are dried and
instead of being fat liquor wet in a hot
stuffing barrel,
they're actually hot stuffed with waxes
and oils in a dry barrel.
Apparently, while dry, the fibers suck
up the fat liquors like a sponge.
Sources like Maverick Leather say that
the whole process takes less time than
the 28-day cycle of Chromexcel uh
followed by the dry hot stuffing
process.
So, understanding that the tanning
methods are similar but different, how
does Chromexcel and Double Shot compare
when felt by a non-leather expert?
I have to say that initially,
the natural Chromexcel felt wetter when
the books were boots were being unboxed.
While Double Shot,
it certainly felt waxier. The Chromexcel
seemed to bleed some oil on hands and
brushes.
Uh even today, both pairs have been worn
about the same amount. Both have been
conditioned in almost exactly the same
way. Uh I condition them with Neatsfoot
Oil about three times a year, and then I
finish it off with Venetian Shoe Cream
and brush them. Uh and even today, the
Chromexcel Oak Street Bootmaker has an
oilier feel you drag your hand over it.
The Double Shot, this Richmond,
while it's still soft in the in the
hand, it definitely feels waxier rather
than oily.
Both brands use similar thickness
leathers. And while the Chromexcel feels
more pliable,
the Double Shot actually feels firmer.
Uh and it provides more structure.
I'm not sure if that's because of the
oily versus waxy feel, but it seems to
me that that the Double Shot
is easier to scratch and it's it's
harder to buff out the scratch. While
the Chromexcel,
it shows a lot of scuffs, right? But
it's a lot easier to use your thumb to
smooth them out. Uh presumably, I think
because there's more wet oils and firmer
waxes waxes in the leather.
Uh in terms of temper, I think
Chromexcel has has a medium temper, me
me medium soft. It needs almost no
break-in when you first put it on, and
it feels
uh remarkably comfortable from the first
wear. You can almost feel it mold to the
knobs and lumps of your feet.
But, this yielding temper also means it
can stretch out over time and um not in
this pair, but I I had a pair of
Wolverine 1000 Mile in brown Chromexcel
uh that really showed some relaxed
structure around the ankle and the
Chromexcel shaft really collapsed into
folds.
Mind you, that pair also showed some
grainy separation around the ankles as
well. So, maybe clicking wasn't exactly
at 100%.
I think the double shot
somehow seem seems firmer in temper, has
more structure.
Not that the Parkhurst required a long
break in, but I just felt that there was
more, you know, fighting back when I was
breaking in this boot.
Having said that, maybe the firmer
temper also avoids loose grain because
there's only a bit showing on the on
this boot across the the fold of the
toes. Whereas, some of my brown and
black Chromexcel boots do show lots of
like wrinkly uh separation.
Now, just before I finish with how these
feel, some people call the double shot a
work leather because PNW brands use it
quite a lot.
Just bear in mind that the thicknesses
that PNW brands use are sometimes double
the, you know, two and a bit millimeter
thickness leathers used here.
Uh and Nick's, for example, doesn't call
it a work leather.
Now, let me compare how these two
leathers look.
First in terms of their color,
both came out of the box looking quite
similar, a sort of pale, buttery, uh
golden light light honey color.
As they wore, and in both cases I wore
them out in Australian summers with a
lot of UV dangerous sunshine.
As I wore them, they both darkened.
But, I feel that the natural Chromexcel
uh darkened more and faster and in a
very attractive way with highs and lows
in the wear patterns.
While the double shot did darken,
it seemed to me to be less dramatic and
it darkened like evenly.
After the first bout of conditioning,
both darkened, but as the uh mink oil
dried, the double shot remained darker
and again, you know, more even.
Over time, I continue to find that the
Chromexcel seems to darken to a golden
caramelized honey brown,
uh better, faster, and the patina is
showing a lot more than on the double
shot.
Again, as I said at the beginning,
it may be the batches or the choices of
hides,
but take this pair cuz
where is it? The Spalding.
This is only 4 months older than the Oak
Street, but take a look at how that
patina has developed.
I'm assuming that the patina development
is because the Chromexcel has oils that
oxidize faster and the double shot has
more waxes that protect it. I don't
[snorts] really know.
Um even the pull-up, I think you can
see, is much more marked uh in the uh
Chromexcel
and a lot more subtle in the double
shot.
And talking about you being able to see
it, I'm not sure sure you can,
but I find that on brushing these pairs,
not with polish, but just after
conditioning,
the double shot seems to gleam more
easily than the Chromexcel. Again, I'm
guessing that the waxes polish it up
better.
Since I'm talking about how they
compare, I guess I should talk about the
care for these leathers.
I find that if you come home with
scuffs, just because you've been clumsy
and brushed up against something hard, I
can easily use my thumb on the
Chromexcel and with some
vigorous rubbing and a bit of heat from
my thumb, I can remove 90% of the
scuffs.
With the double shot,
they seem to show less scuffs, but if
there is a scratch, it's harder to rub
it off, and I need to wait until I
condition it to uh really look after
those scuffs and scratches.
In regular conditioning of these boots,
I find that the process is totally
similar, to be honest. You brush them a
lot to remove dry dirt, and then you uh
also brush them to redistribute the oils
and the waxes.
And then I use a thin smear of neatsfoot
oil to moisturize both leathers.
I find that neatsfoot oil won't darken
the leather, or if it looks darker, it
will lighten up as it dries and gets
absorbed in a day or so.
Don't forget that Horween uses neatsfoot
oil as one of the products at the end of
their tanning process.
Both leathers
seem to address that uh uh
uh address and absorb the thin smear
well, but if you have any oil sitting on
the surface, just wipe it off.
Then, I use a couple of thin coats of
Venetian Shoe Cream, allow it to dry,
and then brush like crazy.
It's at this stage that I find Double
Shot provides a shinier finish after the
VSC.
At the end of the day, unless you're
looking for a really aggressive patina
to develop, I think for all intents and
purposes, both leathers are comparable.
The differences don't make me prefer one
over the other, but when I look at the
old Parker Sporting,
and I think that this trench boot will
look that way,
I like it for that look.
I think buy Chromexcel if you want a
classic, comfortable heritage boot that
tells a story quickly through
high-contrast creases and quick
darkening.
Buy Double Shot if you want a more
supportive leather that seems to retain
its shape and stay looking clean and
light toned for longer.
So, I hope you like this video. If you
do, I'd really appreciate it if you SLC.
