Ideal for kids in & out of the water. These are shoes designed for the sort of kids who love playing even where it's wet. The upper is made from washable polyester webbing, the lining is quick drying & they are treated with PFC free durable water repellent. They are really comfortable all day long thanks to the EVA foot bed with arch support & the lace lock bungee system with adjustable hook & loop strap. Natural odour control sounds like a big claim but CLEANSPORT NXT uses radical new technology. Thousands of naturally occurring beneficial microbes are bonded to every inch of the surface of the shoe. Nothing happens until the microbes come in contact with sweat, then they activate & break down the organic matter that causes odours then become dormant again until next time. Clever huh?
