The Alpha boot introduces an innovative approach to dive boot design that addresses the needs of both temperate and cold-water divers. Embracing the sport shoe concept, the Alpha boot employs a laced closure instead of a zipper on the body of the boot. The laced closure enables you to achieve a snug, comfortable fit, and then tops it off with a Velcro strap on the ankle for maximum security. The unique two-layer construction combines neoprene and nylon along with anti-abrasion fabric on the outside to create a boot that’s both flexible and durable. On the inside, a Diamond Span lining improves warmth and comfort, plus dries quickly. The anti-slip sole provides security on wet surfaces, and additional protection forthe toe and heel areas.
