The Pearl Izumi P.R.O. Barrier WxB Shoe Covers will keep your feet protected even the worst conditions. The weather won't deter your efforts when you opt for the warm dry comfort of Pearl's all-new P.R.O. Barrier WxB Shoe cover, a winter-riding roadie's requisite companion. Water and wind don't stand a chance against the seam-taped fabric exterior, plus the fleecy interior keeps feet cozy. A patented two-stage hook and loop closure and all-over stretch allow for a custom fit with zero slop, and a rubberized toe gives traction where it's needed to prevent slipping when you stop.
