Make a statement on the field with these bold multi-coloured knee-length wacky socks! These knee-length sports socks are ideal for rugby, football, and hockey. They feature a fully elasticated turnover top so your socks won't fall down on match day. All our sports socks have COOLMAX Pro ultra-high performance padded footbeds that regulate temperature, keeping your feet cool and dry throughout your match. Made in Great Britain from 95% polyamide and 5% elastane which ensures a snug and soft fit on the leg, the socks can be worn with or without shin pads. Our knee-high socks also feature external smooth toe seams to make blistering a thing of the past. All our socks have an elasticated ankle for support and an elasticated central foot band to help reduce slippage. Whatever your sport or age, there's a WackySox for you. Our socks are ideal for all children, men, and women with bold designs to suit every occasion. Wacky by name and appearance but certainly not in terms of function and performance.
