The You Got My Back Sidewalk Surfer features the look of a shoe with the easy on-off convenience of a sandal.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.
