The Propet Women's Ped Walker 5. Two removable insoles let you customize your fit: the top layer Rex Insole has built-in memory foam cushioning and enhanced arch support, and the Polycork base is made with charcoal to help eliminate odor and absorb moisture. Extra comfort comes from the roomy last (shape), a stretchable neoprene vamp that conforms to your foot, and an adjustable hook-and-loop instep strap.
