With over 40 years of history as the original indoor/outdoor après sport casual wear, the Acorn Slipper sock is a tried and true heritage item shaped by the Maine experience. Genuine suede sole is stitched to a cozy ragg wool or cotton blend upper. Rib stitching at shaft creates a close fit that helps retain heat. Leather sidewalls help repel water and other liquids. The best part? These acorn socks come with built-in Cloud Cushion multilayer memory foam footbed for adaptive cushioning where you need it most.
