These boots have a fine light, lively feel to them. They are at least as stiff as my previous boots, Scarpa T-!s and definitely lighter. It took a bit of work to get the right fit. For area skiing or yo-yo ing I needed to add an extra footbed (from my running shoes). However on a weekend of epic skiing at Mt. Washington and Mansfield this proved to be too much (both days my feet were in great pain by the afternoon) and I had to take out the extra liner. What I like best is the feel of the way the bellows flexes-very smooth. This makes it easier to quickly pressure the uphill edge. The buckles are OK-not totally crazy about them. It is very hard to close the top two on their tightest two settings. The actuation of the walk setting is good. The manual that came with the boots refers to two locked settings for ski mode-but there is only one. I called the company and they report that a new bar with the two settings (I missed the more forward/aggressive one) will be available this fall. Putting the boots on is difficult. I found that the easiest way to do it was to take the liner out, put that on and lace it up, and then insert foot/liner in the shell.
