As a recent convert to AT, I am more than pleasantly surprised by these boots. So light and responsive, while being super comfy. The magazine reviews complain of the buckles, but I think the reviewers need some occupational therapy. I think the buckles are perfectly fine. They are extremely easy to switch from the ski/walk modes. I am 5'7" 175 lbs, and ski aggressively. After alpine skiing my entire life, I would recommend these boots to anyone - veteran and beginner alike. I have a very wide foot and high instep, usually struggle with heel slippage. These almost feel custom fit, before the heat molding. If you weigh more than 175, and are more aggressive, you might want a beefier boot. A few times they felt a little soft. 100% satisfied with my purchase.
