I would consider this a medium flex boot, which I like. They worked well for me in the backcountry and around the mountain, including open groomers and in the park. Although, the boot sole is a bit thick, so I don't get the "feel" of the board that I have had in some other boots, but this also benefited when landing airs a bit flat. Not a big fan of conventional laces anymore, as I'm constantly adjusting them these days and I can't seem to get the upper boot tight enough. Do they make these with a Boa system? Also, the inner lacing system is only decent, but not efficient or well designed as some other boots (ahem..Burton). I found that the inner lacing system doesn't tighten evenly, causing some discomfort. I have only used them a few days though so this will probably get better. True to size.
