Breathable mesh and synthetic overlay upper. Seamless mesh lining with edge free tongue to prevent rubbing and chafing. External heel stabilizer for added support. Intrepd insoles feature an open cell PU top layer with structured TPU bottom layer designed to work together to guide the foot with medial and lateral support, plus a deep heel cup to maintain proper alignment and control pronation. Also includes an EVA spacer to customize the fit. The mid foot carbon fiber shank aids with both torsion and propulsion, working with the DuroCloud ETPA foam technology to promote lower compression so the midsole expands more quickly, maximizing bounce and overall energy return. Rubber sole absorbs impact and offers excellent grip and traction on both indoor and outdoor surfaces. Diabetic friendly, double insoles. | Propt Men's Propet DuroCloud 392 Sneakers, Grey, 11EEE Propét Men's Propet DuroCloud 392 Sneakers
