If you're surfing a lot of reefs in a hot climate then reef boots are a necessity Xcel's version has a drawstring at the ankle & a velcro tab over the instep so you can tighten them up & make sure they're not going anywhere once you're out in the line up. The thick rubber sole will protect you from most reef & make sure you can walk out with complete confidence & the new higher ankle cuff also helps prevent scratches or cuts from uneven surfaces.
