I contacted the folks at Context and was told that the horse butt consists of 3 layers and that shell cordovan has 2 layers removed to expose the shell membrane. The leather they're using supposedly has all three layers intact.
I'm torn between the brown chromexcel Indys and the natural chromexcel Indys, both with commando soles. Any thoughts on the versatility of the different shades? Any difference in durability of the finishes? These would be used during Michigan winters.
