New 3D rubber reinforcements for this new 2020 NORTHWAVE DECADE SL GREY to make this boot bulletproof. While keeping its typical construction with the flex window, but updated design, this year it comes with the Stamina outsole for a more direct feeling with the bindings and board. We also pimped it with a fresher, newer look so it never gets old. Thanks to the new spats, its waterproofness is assured by neoprene material that prevents snow, ice and water to get stuck on the tongue and eventually penetrate the boot. Equipped with the new Biomap asymmetrical Tongue for a more progressive flex and the CAB5 heel retention system for a secure lock of your foot. TF3 Liner.
