The O'Neill Heat boots are an excellent value for beginners and serious surfers alike. 100% superstretch neoprene for maximum flexibility in the water and a durable, yet soft sole, these boots will give you all of the performance most users will ever need. The seams are sealed and blindstitched to prevent water from trickling in. A shin strap helps tighten boots to the leg to further prevent flushing. A heel pull tab assists in pulling on the boots.
