Velox Swim fins from IST are children’s fins that are made with the same quality and attention to detail as adult gear – they’re durable and made to last and take whatever your child can give it. In the water or on the beach or at the pool, kids love Velox! The Velox has a balanced blade that’s vented for more propulsion. Comfort is built-in; there an open toe box for easy draining while in the water.
