Vibrant run socks for every pace
Whether you're easing into a warm-up jog or digging deep on a tempo finish, the Prism has a way of making your feet feel properly looked after. This lightweight running sock from Darn Tough features an updated tech foot that delivers a smooth, flexible fit — supportive enough to hold form at speed but comfortable enough for a cool-down shuffle. The cushioned underfoot adds some welcome softness for longer efforts, while the merino wool blend keeps things breathable, dry and fresh even when you're putting in the hard yards. The bold, colourful design adds a bit of personality to your kit, and the micro crew height sits just right above your trainers. Performance fit means no faffing with readjustments mid-run, and the lifetime guarantee means you're set for the long haul — quite literally.
