Breathable comfort and innovative performance are mixed with a contemporary, sneaker-style aesthetic in the ECCO MEN'S GOLF BIOM® C4. For 360-degree breathability and 100% waterproofing, the GORE-TEX SURROUND® construction is combined with the EXHAUST GRID that enables air ventilation 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.
