Adidas’s Response ADV is aimed at riders of all ability levels who are looking for a mid flex all-terrain boot that delivers exceptional performance across the whole mountain. Its advanced upper features a combination of articulated construction and the acclaimed Dual Boa closure system. This innovative design creates a progressive flex combined with unrivalled foot-hold and support to deliver a progressive yet dynamic riding experience. Now to ensure the Response delivers class-leading levels of fit and comfort, Adidas utilise their Silver Level heat mouldable Ultron Liner with Inner Ankle Harness. This high-performance combination not only delivers that classic Addidas comfort and fit but it also ensures that whatever energy you put into the boot it’s going to get directed straight to the board.Dual Boa ClosureSynthetic Leather UpperContinental Rubber OutsoleSilver Level Ultron LinerInternal Ankle HarnessCord Lock Articulated Cuff3D Moulded TongueRubber BackstayStiffness Rating: 5/10Fit Profile: Slightly wider in the forefoot compared with the higher end Adidas boots but still with that tight heel and shallow instep. The Intuition liners will let you customise the fit and feel more than a lot of other heat mouldable boots so make sure you take advantage of this process to optimise the fit and feel of the boot.Sizes:Response 3MC ADV Specification: Dual Boa™ ClosureThe tongue mounted H4 Coiler is the top closure point for the boot. Geared at a ratio of 4:1, it tightens the top half of the boot quickly and effortlessly. To tension the bottom half of the boot, the side mounted Coiler has been specifically designed to provide increased leverage to let you dial in the perfect tightness. This Dual Zone system gives you complete independence of the top and bottom halves of the boot, allowing you to almost instantly dial in the perfect fit and flex for whatever terrain you want to ride.Silver Level Ultralon LinerThe Ultralon foam offers superior thermoforming compared to the generic foam most manufacturers use. This creates a better fit, as well as being more resistant to pack out after heavy use.Inner Ankle Harness with Speed LacingThe Inner Ankle Harness is designed to ensure effective support and increased heel lockdown.Cord LockThe Cord Lock is an innovation for Adidas for this season and is designed to step up both response and support. This advanced technology attaches the inner harness closure direct to the tongue, improving the integration between the shell and the liner.Articulating CuffThis flexible cuff divides the upper and lower sections of the boot. It allows the upper to flex naturally without pushing out the lower part of the boot. This gives smoother power transfer and reduces wear on the shell.Continental Rubber OutsoleSturdy Continental™ Rubber outsole for optimal grip on snow and ice.
