Cressi Unisex's Boy's Agua Fins-Aquamarine, 31/Size 32, Kid 12.5/13.5 (31/32)

The Cressi Agua fins are top of the range fins for beginners, snorkelling and swimming. They are made of polypropylene for the blade and very flexible thermoplastic rubber for the wedge and longitudinal ribs. Polypropylene is a light and resistant material and its main dynamic characteristic is the rapid elastic return of the blade, which translates into a fluid, agile and efficient flapping. The structure of the fin places the foot pocket under the blade, protecting the foot from any bumps or rubbing against the bottom and extending the useful surface of the blade over the instep. Features:- Very soft and comfortable elastomer (thermoplastic rubber). Applied to the upper area of the foot pocket and the lateral stabilisation ribs of the fin during swimming- Fully rigid sole to avoid cramps and to transmit effort without energy loss through elastic zones.
