The Problue Deluxe 5mm Boots have been constructed from a thick 5mm neoprene to retain heat where it is needed most in cold conditions. The anti-slip soles of the boot have been vulcanised to provide grip in and out of the water. The grip runs partially up the side of the boots for superior angled grip, whilst covering the heel and toe of the boot where the most wear is experienced. The grip is effective in both directions making it an ideal boot for boat diving. A glued and blind stitched construction adds to the durability of the boot, and the derlin zips of the boot are resistant to rust.
