An improved flats boot based on our long-standing and best-selling Christmas Island Bootie. Made of Airprene and vulcanized rubber. The Airprene upper allows water to flow freely through the boot but keeps sand and grit out. Easy on-and-off with a YKK® side zipper secured at the top by a low-pro TPU/VELCRO® Brand fastener to prevent line snags. The sole and sidewall are a heavy-duty ridged rubber to protect against coral abrasion and offer excellent stability, but this version is much more flexible than its predecessor for comfort and “feel” on uneven surfaces. Comes with a reusable mesh carry bag.Airprene and rubber. Flush with fresh water. Imported.Men’s whole sizes 5-14. 8" high. Weighs 32 oz. in size 10.
