The formal version of shape-ups (the shoe with a convex sole that tones your legs while you're just going about your everyday life). Dress-ups come in brown, black, and cordovan and should be polished before attending the most important meetings and functions. Dress-ups can be worn with a suit and tie or just a pair of nice slacks. They allow the wearer to tone his or her legs even in the most formal settings.
