Finally, a real advance in boot design that works.
I’m ann advanced skier and these boots are freaking awesome. The BOA system works brilliantly making adjustment simple, and spreading the pressure much more evenly over your foot. Reaching down to just twist the BOA knob for incremental adjustments is such a pleasure after fiddling with buckles that are either too tight or too loose.
Do not buy!
Absolutely terrible boot. Was recommended by a boot fitters because I have a wide foot but this boot is still way too small. The BOA lock is awful and applies pressure right at the dial
