SeaChange is the first and almost completely recycled collection. SeaVees partnered with SeaTrees, a non-profit who works to restore coastal ecosystems and ocean health globally - by regenerating one foot of kelp forest for every pair of shoes sold. Lace closure and recycled cotton canvas lining for all-day wear. Contoured, cushy foam footbed with extra heel-strike cushion. Includes an exclusive cooling system with perforations for breathability and cooling airflow channels for extra cool comfort. Bouncy, original power-grip outsole made from recycled rubber. Imported. Measurements: Weight: 12 oz Product measurements were taken using size 8, width B - Medium. Please note that measurements may vary by size. Weight of footwear is based on a single item, not a pair.
