The Hollis Rock Boots provide excellent protection to drysuits fitted with neoprene socks and also help to reduce air migration to the feet when inverted by elimating air pockets. Tough canvas upper and deep rugged rubber sole are tough enough for any dive site. A Thick Rubber Sole protects the bottom of your feet and offers extra traction when moving around over slippery surfaces. A protected toe cap helps to prolong the life of the boots when you have your fins on whilst a fin cleat on the heel ensures your fin strap always remains in place. Chunky laces hold the boots in place.
