boost™ Foam Midsole - Unlike standard EVA foam, boost™ provides consistent and responsive cushioning across dynamic temperature ranges from subzero cold to punishing heat. This innovative foam technology increases your energy return and improves edge-to-edge responsiveness.
Gold Level Ultralon Heat-Moldable Foam Liner - Ultralon's fine and consistent, dual-density cell structure conforms to the contours of your foot for a comfortable, customized fit. The inside is lined with Tech Mesh for superior breathability so you can push harder without overheating.
Articulated Cuff - The articulating cuff shell features separate upper and lower zones that flex easily together instead of bowing out, delivering a softer but more supporting flex and a better more constant fit.
Rubber Backstay - Helps prevent slippage between boot and binding highbacks.
Rugged Multiderectional Rubber Outsole - Grippy, rugged multidirectional rubber outsole for traction on snow, ice and top sheets.
Inner Ankle Harness - Secure your foot inside the liner and shell for a no-slip fit.
1:1 Boot Fit - 1:1 Boot Lasting secures a better fit and heel hold by following the natural contours of the foot. If you wear a 10, you're going to want to buy a 10, it's as simple as that, these boots fit how you want boots to fit.
The ADV has great heel lock and fits comfortably. I wear a size 11.5 shoe and got an 11 boot.
Definitely recommend trying them out, they're expensive, but they're worth the cash.
My knees and back love the boost in the boots.
