Breathable mesh and synthetic overlay upper. Seamless mesh lining with edge free tongue to prevent rubbing and chafing. External heel stabilizer for added support. Intrepéd™ 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.
