The Cressi Metallite Boots Black 2.5mm can be used with both closed foot fins for greater warmth  and to protect the skin from scratches and chafing, as well as with  firm-soled boots, using open-heel fins.In this case, warmth is  considerably increased and it is also easier to put on your wetsuit.

The Avanti HC Pro forms a large hyperchannel when kicking, for an increased performance/effort ratio! Including a soft ergonomic foot pocket for extra dive comfort!
