Lupo PRO is an advanced version of the Lupo series which mainly caters to the most serious freeride skiers. The big difference is that Lupo PRO has a shell cast in 100% PU (HD) with a Polyamide/Composite carbon fibre cuff. Obviously it also tech inserts if you want to use a touring/hybrid binding and the same 67 degree walk mode as other Lupo models. For those who loved Krypton PRO but was longing for a walk mode the perfect boot is now here. The obvious choice for Ian Mcintosh & Markus Eder. Comes with a volume-reducing extra insole and an extra wedge for the back for those with narrower calves or riders looking for a more forward angle.
