The Sidewalk Surfer by Sanuk is a hybrid shoe/sandal combination featuring a shoe upper on a sandal bottom. This patent pending design combines the year-round style and protection of a shoe with the natural comfort of a sandal. The sandal bottom allows your foot to bend and flex the way nature designed you to walk. And the loose fitting upper allows your foot to spread so it can absorb shock naturally. They are the most comfortable shoes - I mean sandals - we've tried in years. The Pick Pocket features a hidden stash pocket, coated cotton uppers don't flinch at a little weather, and jean-like stitch details.
