The Akona 6mm Deluxe boot features 6.5 mm nylon II neoprene and strong glue and blind stitched seams for a highly effective water seal. This leads to reduced water exchange, resulting in cozy and toasty feet. The new design of these boots ensures a contoured and snug fit, enhancing comfort and warmth.
