Great, but seem to loosen a bit
Most comfortable boot I tried on in the store. Just tried them out tonight on the slopes, awesome!! So light and small, but so responsive and comfortable. Major upgrade over my older boa boots.
I wear a size 14 mountaineering boots, but a 13 fits me in these. They run bigger than the high-end K2 and DC boots I tried on in the store. Perfect fit.
Note I also tried on the Burton Drive Xs and there was a night/day difference in comfort, with the Ions winning.
Only problem so far is that they seem to loosen up a bit as I ride. Kind of sucks, not sure if it's something I'm doing. I usually tighten one of the boots at least once after a few runs, or just deal with the loosening. If you have advice on keeping them nice and tight how I like it, let me know!
