The Reef Boy's Grom Roundhouse Sandals are just like the Men's Roundhouse, but smaller. Groms can really dig their feet into the Grom Roundhouse sandals, with a synthetic strap and a soft jersey lining for comfort. They'll love the soft Swellular cushion footbed too. Boys sandals with a high density EVA outsole will outlast even the most energized kid. The first four sizes (3/4, 5/6, 7/8, 9/10) come with attached heel strap.
