This happens with my shell jumper boots, but no other pairs (including boots and shell shoes). It only happens when I'm stepping down from a curb or stairs, toe down, so it doesn't bother me too often.
I have a pair of Noix wholecuts from Leatherfoot, and it really is a gorgeous color. I love the Noix chukkas from Gentlemen's Footwear, too. By the way, how do you pronounce Noix? Is the "oix" like the "wah" sound?
While Carmina's hatch grain looked sorely disappointing to me, I have to vouch for the scotch grain; I have those black grain bal boots that Epaulet did for 2 runs last year, and the texture and quality are phenomenal.
