KE UNEEK M adapts to your feet for the perfect fit, with innovative two-cord construction providing freedom of movement. The lightweight midsole and higher-traction rubber outsole deliver durability and comfort. The shoe features a metatomical footbed design. This internal support mechanism is anatomically engineered to provide excellent arch support and cradle the natural contours of the foot. The shoe can feel 1/2 a size too small, so we recommend you order it a 1/2 size larger than your usual size to ensure the perfect fit.
