Thanks for the advice. I'm definitely saving up for a black pair to go with my black cherry. Being able to rotate would certainly help. I don't have a foot sweat problem, but I'm used to fully drying out my shoes between wearings to keep them in good shape.
I put Sno Seal on my black cherry Beckman's last night, and I know some wanted pics of them after application to see whether they darkened, so here you go. (Orange and bananas for color reference.)
