KEEP YOUR FEET DRY – The hallmark of our Super Breathable socks is the DRYMAX technology. It features dual-layer, moisture wicking knit fabric designed to move the moisture from the inner layer (close to your foot) to the outer layer where it can evaporate. Keep your feet up to 25x drier than any other sock in the world.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 socks are proudly made in the USA using specially formulated materials: 73% drymax-olefin/11% polyester/11% nylon/5% elastane.COMFORT YOU CAN FEEL ÿ Engineered to be the perfect running sock. Flat seam provides chafe-free comfort for your toes while the roomy Y-heel keeps the sock in place. Double cushioning under forefoot and toes help absorb impact and increases your comfort. Breathable compression arch band supports your foot and increases blood flow while the elastic band around the ankle never sinks down. Lastly, the MicroZap Antimicrobial technology permanently defeats odor causing bacteria.LOW CUT STYLE IN 3 CUSHION LEVELS ÿ The low cut style gives a modest rise above the shoe collar and sits right at the ankle bone. Low Cut socks come in 3 available cushion levels: 1-Thinnest, 3-Thin cushion, 4-Medium cushion. These varying levels of cushion allow each athlete to choose the level of support they need for their specific needs. SIZING: please reference the sock size chart image to match the size of sock you need to your shoe size (available for both men’s and women’s).1,000 MILE BLISTER-FREE PROMISE – We believe in creating the best fitting socks ever.
