Under Armour’s Performance Tech Crew socks sit in the brand’s training range, aimed at everyday gym sessions and sports where you want a secure fit and less irritation inside your trainers. They compete with the usual Nike and adidas multipacks, but lean more towards a “sport sock” feel than basic cotton crews. This is a 3 pack in white, sized for UK 4 to 7.5 (EU 36.5 to 42), so it covers a broad unisex fit for most adults.

Who are these socks for?

Best suited to people who train regularly, walk a lot, or simply get through socks quickly and want something that stays put. A crew cut gives more coverage than ankle socks, which can help if your shoes rub around the heel collar, and it also works well with boots and higher top trainers.

  • Pack size: 3 pairs, useful if you rotate socks through the week
  • Fit range: UK 4 to 7.5 (EU 36.5 to 42), a flexible unisex size bracket
