The Problue Deluxe Boots are a heavy duty 3.0mm dive boot. They have a durable, flexible and vulcanised anti-slip rubber soles. The pattern of the soles goes in both directions for added traction which makes them ideal for boat diving. The grip of the sole extends up the side of the boot to provide angled traction. Durable rubber caps on the heel and toe of the boot have been included for grip and protection of the neoprene material. Problue have exploited glued and blind-stitching technology. These boots go well with most open heel fins on the market.
