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.Acerra 3ST 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.Boost MidsoleBOOST is Adidas’s state of the art cushioning technology. Originally created to dampen out shocks from high impact sports such as running, this advanced thermoplastic polyurethane (TPU) compresses under pressure for better shock absorption and instantly bounces back to its original shape.These characteristics make it the perfect performance material for snowboard boot construction.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.Rubber OutsoleGrippy, rugged multidirectional rubber outsole for traction on snow, ice and top sheets.Gold Level Ultralon LinerManufactured from dual density Ultron heat mouldable foam which forms to the shape of the foot giving a fully customised fit.Inner Ankle Harness with Cord Lock 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.Slip Free RideRubber backstay helps prevent slippage between boot and binding highbacks.
