Breathable comfort and innovative performance are mixed with a contemporary, sneaker-style aesthetic in the ECCO M GOLF BIOM C4, the next generation of the BIOM COOL PRO. For 360-degree breathability and 100% waterproofing, the GORE-TEX SURROUND construction is combined with the EXHAUST GRID that scoops fresh air towards the sole of your foot. Crafted from ECCO Performance Leather and a new, super-stretchy mesh sock, the hybrid is set on the progressive ECCO MTN GRIP outsole, and powered by BIOM NATURAL MOTION Technology.
