These socks are made from a high-quality blend of cotton, nylon, and elastane, so they're both soft and durable. Whatever you are doing (running around the playground, skateboarding, or chilling at home) Fox-Man socks will keep your feet comfy and cool. They're designed to fit most young people, aged 7 to 12 years old (although my mum is a size 8 women's and she wears them too!).
