Black, pink and blue striped Wacky Sox with an ultra high performance foot made from 75% Coolmax and 25% Polyamide. Coolmax is a moisture management fabric featuring advanced wicking technology which helps keep moisture away from your skin to keep you dry and cool, so you can play harder. The leg of these socks is 5% Elastane 95% Polyamide. Elastication around the centre of the foot helps avoid 'bunching' or slippage, while the elastication around the ankle provides additional support.
