I've owned four pairs of Bass "Bucks" and have worn each until they were literally falling off my feet. The pair that I am returning today is the first pair that I've purchased with a new design. While the shoes are advertised as "leather" and past pairs have been almost all suede, the balance of these is "man made materials." They are rigid and uncomfortable. Moreover, there is a bizarre new tread that look like golf cleats. I'm switching brands.
