I've had several people hit me up for comparison shots of the Role Club RC2307 and RC1940 profile to assist them in choosing the right last.
The RC2307 (left) has a low-profile toe box, which will flatten with wear. The leather is slightly tighter in this area due to the low profile.
The RC1940 last is reminiscent of 1940's / 1950's unstructured bulbous toe box that will ultimately lead to a flat, squarish toe overhanging the welt (especially when the leather welt shrinks and molds when exposed to water)
I threw in a shot of the Woodsman heel as well. Both boots bear the same amount of stacks, but my studded RC1940 only looks taller because of the double leather sole. I asked for this profile to match an original midcentury Chippewa.
Leather becomes extra stiff when dried after being exposed to inclement weather. Depending on the type and amount of chemicals used during the tanning process, leather can develop a stiffness reminiscent of decades-old Horsehide. Chemicals used in Chippewas Cowhide during their "special tanning" process just sixty years ago leaves their hand-selected leather stiff with desired creases and wrinkles leaving collectors to believe they are seeing and feeling Horsehide -- Chippewa never used horse leather on their boots.
I added this information because it's relevant to the amazing Horween Chromexcel Horsehide Brian used these particular boots. This type of leather is tanned with the more-than-normal amount of oils and greases, so it's important to wear them hard and often ... but don't force it. Even with my limited wear, these boots are looking pretty amazing.
