ULTRA COMFORTABLE ? To create the world’s most comfortable sock, we focused on the details. We start with a moisture management fiber to keep your feet cool and dry all day long. Then we add in strategically placed ventilation panels for even more breathability and comfort. Mix in half cushion protection padding along with arch support for a nice snug fit and tie all together with a seamless toe box and there you have it, a recipe for the world’s most comfortable socks! NO MORE BLISTERS – Since we don??t use cotton in our socks, you won??t get blisters. It??s that simple. Cotton absorbs water which causes your foot to slide and is how you get hot-spots and blisters. Our ultra-premium socks are made using specially formulated materials: 82%-Polyester/16%-Nylon/2%-Elastane. PREMIUM QUALITY- Like all of our R-Gear apparel items, the super plush socks are made with quality materials designed for athletes and runners. Once you put these socks on, you will feel the difference. NO SHOW, TAB STYLE IN 1 CUSHION LEVEL ? The no-show style is designed to stay hidden below the shoe collar to keep those sock tan lines low. The tab is an additional portion of fabric that protect the upper heel/Achilles area of the foot from rubbing. These socks are only available in Level 2 – Thin Cushion. 1,000 MILE BLISTER-FREE PROMISE – We are committed to making the best fitting socks ever. If you are not completely satisfied with our socks, simply contact us and we will make it RIGHT!
