This 5mm zippered neoprene bootie features a specially formulated 7mm-thick vulcanized rubber sole for traction on both decks and flats. The unique fiber midsole and vulcanized rubber toe cap and heel counter provide ultimate foot protection. Vented side panels help cool the bootie and provide for quick drainage, while the full-length zipper dam helps block out scree. Strategically placed triple-glued and blind-stitched seams are comfortable and durable. A rubber heel lug holds fin straps in place for tube fishing.
