The UYN Free Flow Metal shoe attracts attention and repels heat. The outer layer of the upper is made with the special Argenthon yarn that reflects heat radiation, ensuring a dry foot even on hot summer days and a unique style. Inside, the Natex fiber and the hemp insole promote rapid moisture dispersion and reduce the formation of unpleasant odors. UYN has managed to eliminate every seam, creating a high-performance shoe with the comfort of a sock. Composition: 100% fabric.
