Cressi Isla Neoprene Boots keep feet warm during water sports. The back of the heel has a built-in fin strap holder to fit perfectly with open-heel fins when scuba diving. Long-lasting rubber reinforcements on the toes and heels provide protection against wear and tear. Soft, double-lined neoprene construction offers ideal thickness for warmth and durability. A zipper extending from the sole to the ankle ensures easy on and off. A thin flap seal under the zipper acts as an effective barrier against water seepage.
