CEP 3.0

Our take If going fast on snow-packed trails is your thing, snag a pair of these speed-friendly socks. The 3.0 is thicker than most trail running socks we’ve used, so it kept our toes in the comfort zone on subzero missions in the Washington Cascades. And because this is a compression sock, it enhanced blood circulation and prevented cramping on a 36-mile race with 16,000 feet of elevation gain on Washington’s Tiger Mountain. Even on a grind like that, the asymmetric toebox—more space for the big toe, less for the little—formed to our foot better than other socks, helping us stay hot spot-free mile after mile. The 3.0’s Y-shaped synthetic yarns form channels that quickly wick moisture.

Trail cred “Despite the compression this sock was a breeze to take off after each training run, and it never bagged out,” one tester says.
