The men's
These Ion all-mountain freeride boots are supported by their (8/10) stiff flex and their instant reactivity which makes them ideal for creating precise lines in the backcountry. The EST® midsole not only thins down the sole for a lighter weight but it also particularly improves board feel all while lowering your centre of gravity.
The extremely lightweight Life liner with the Total Comfort construction will be very comfortable from the very first time you wear them. Since comfort also requires a high level of heat retention, the Ion Boa® features Sleeping Bag thermal insulation and a DRYRIDE™ Heat Cycle™ lining to keep you nice and dry. Handy when you need to walk through the snow to get to the starting point you had planned out!

Lacing:
- Dual-Zone BOA Coiler™ closure system: the boot consists of two distinct lacing zones which can be independently adjusted by turning the dial, this gives a customised fit in both the upper and lower sections of the boot.
