The Smartwool men's NO SHOW Socks are the 'brand's lowest-cut design - with a completely "hidden" height. These socks are made from a breathable, warm yet airy merino wool blend featuring nylon for strength and elastane for durable stretch. Smartwool placed an internal silicone heel gripper to help keep socks in place. Seamless openings prevent pressure points and blisters. Under your foot, supportive arch braces make these socks even more comfortable. No Show socks are perfect for rocking with your slip-ons and sneakers.
