Smartwool's lowest-cut sock yet, with a "hidden" height. This secret in your shoe is a non-cushioned No Show sock that's perfect for ballet silhouettes and other flat shoes. It features a large internal silicone heel gripper designed to help keep socks in place. The secret sleuth also has a seamless opening made to help prevent those pesky seams from putting pressure on the top of your foot. The merino wool wicks moisture to help prevent smelly feet.
