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 enables air ventilation towards the sole of your foot. Crafted from ECCO Performance Leather and a super-stretchy mesh sock, the hybrid is set on the progressive ECCO MTN GRIP outsole and powered by BIOM® NATURAL MOTION® Technology. The BOA® Fit System allows for simple adjustments and an easy on and off.
