Mother Nature is always in flux, but mankind is both smart and adaptable. In other words, whenever she changes her mood, we always have the right tool for the job. And when that job is protecting against blustery, cold conditions, the right tool is our Deflect(TM) Comp Shoe Covers. Compared to our Element line of shoe covers, Deflect(TM) places more of a focus on wind resistance, so you&';ll find a stretchable construction with lightweight insulating properties. And to make getting in and out of the covers easy, we also included a rear zipper. Abrasion-resistant bottom and toe panels increase the covers&'; lifespan A universal cleat opening makes these covers compatible with either road or mountain shoes. Rear zipper closure makes getting the covers on and off a breeze. Fabric Content: MAIN 100% Nylon - OTHER 100% Polyester - SOLE 92% Polyester, 8% Spandex
