The Ion is consistently our fastest selling high end boot due to the incredible features and performance packed into this all mountain master. This year Burton have teamed up with Tire makers Pirelli to create a tire inspired tread design with a race grade rubber compound for superior traction. Using a Shrinkage Tech EST optimised midsole for total synergy with EST bindings, the Ion now has New AutoCANT Cardinal Cushioning that uses Dual Density EVA to settle your foot into a more relaxed and comfortable position in your bindings for greater control and less fatigue. The Shell is constructed using New Total Comfort Construction and incorporates Outer Shell Pressure Relief Panels and Super Grip Toe for total comfort and excellent coupling with over the toe straps. Internally the Ion Boasts a high end, fully heat mouldable Infinite 4 Liner that wonâ€™t break down or pack out and Dry Ride moisture wicking tech so your feet stay comfortable and dry no matter how hard you ride.
