These water socks are suitable for all types of water sports to keep your feet warm. The back of the sole features a special design that perfectly fits fins with an open foot pocket for diving. Both the toe and heel areas are reinforced with durable rubber, providing protection against wear and tear. They are made from soft, double-lined neoprene and have a practical zipper running from the sole to the ankle, making them easy to put on and take off. A thin seal under the zipper prevents water from seeping in through the zipper. A strong, non-slip strip covers the entire sole.
