The Scubapro Everflex 5.0 diving boot is an ultra-comfortable dive boot with an arch design which closely matches the foot's natural anatomy. The wide foot pocket creates a cramp-free fit, even for wider feet. Made from X-Foam, a limestone neoprene, petroleum-free, and compliant with strict PAH requirements. Scubapro was the first to offer this, better protecting divers and our oceans. Pliable neoprene also makes for easy donning and doffing. The thinner (3.5mm) neoprene around the ankle prevents bulkiness where it overlaps the wetsuit leg. The attractive diamond span interior improves warmth and comfort. A heeled sole provides reliable grip and the outside of the toe box is cushioned and protected against abrasion. Heel cap includes a molded fin strap keeper to eliminate strap slippage. All seams are glued and sewn for strength and durability. The no-zip design includes a webbing puller loop to make donning easy.
