There's plenty of roomy comfort, thanks to the Drew Plus Fitting System which offers two removable insoles--one is a moldable, dual-density insole and the other one is a 1/8 EVA filler. Use one for added depth or remove one for double depth. A Dri-Lex lining wicks away moisture and provide a dry and healthy foot environment. Plus, the steel shank and firm heel counter provides added stability, while the rubber outsole delivers traction. Orthotic and Diabetic-Friendly.
