Island Surf and Sail's flagship wetsuit boot for warm water conditions (>60F), the 2MM Custom Reef provides heavy-duty protection against sharp sea-floor in an ultra-light, barely there package. Surf, SUP, Kite, Windsurf, Kayak: the Custom Reef lets you focus on performance with no worry of shredding your feet. Island Surf and Sail's obsession with booties means the lightest, best-performing reef boot on the market has stepped up several notches for 2019, featuring improved board feel, grip, flexibility, comfort, puncture resistance and durability. How'd Island Surf and Sail make the world's best reef boot even better? 1. Island Surf and Sail's natural rubber sole pods are made with a softer, tackier, more flexible compound for improved traction both on a board and on slippery rocks. 2. Island Surf and Sail's heat-moldable Thermo Foam has also been updated with a softer, more comfortable formula which stays soft in colder temps. 3. Solite has completely redesigned their velcro ankle strap, co-molding the textile strap to the rubber sole and introducing a flexible, durable Tatex-coated hook strap for a stronger hold. 4. All rubber sole-pods on the Custom Reef are co-molded with a puncture-resistant laminate which wards off urchin spines and other sharp objects while still maintaining barefoot-like board feel. Recommended Water Temps: 60+F. Sizing Tip: Order your regular shoe size or 1/2 size down. For example, if you are a size 10.5, order a 10. Women should order 1-1.5 sizes lower to convert from Men's sizing. So if you are a Women's 8, order a Men's 7. If you are a Women's 8.5, also order a Men's 7.
