Breathable comfort and innovative performance are blended with a contemporary, feminine and sneaker-style aesthetic in the new, slim ECCO WOMEN'S GOLF BIOM C4 BOA SHOE. For 360-degree breathability and 100% waterproof protection, the GORE-TEX SURROUND® construction is combined with the EXHAUST GRID that enables air ventilation towards the sole of your foot. Fashioned from ECCO Performance Leather and a super-stretchy mesh sock, the hybrid comes with the BOA® Fit System, which delivers micro-adjustable precision fit. Set on the progressive ECCO MTN GRIP outsole, the ECCO WOMEN'S GOLF BIOM C4 BOA SHOE is powered by BIOM® NATURAL MOTION® Technology and you have the option of removing the insole for extra width.
