These boots are amazing. While offering plenty of comfort and flex hiking up to reslay that kicker, they're a snug fit, so you'll have to take care when removing them after a long day of riding. I experienced virtually no heel lift with these after getting them appropriately tightened down. The Lock Down Speed Lace mechanism at first seemed flimsy and likely to break, but it held up fine and resulted in an amazing fit surrounding the ankles. I also suspected that as a sacrifice for weight and comfort these boots would be a little thin, possibly meaning cold wet feet by the end of the day...well, this turned out not to be the case. They're super warm, made from quality materials, and kept my feet toasty each day on the slopes. I cannot stress how unbelievably comfortable these boots are - not to mention they're lightweight, meaning you can pretty much fly all day. Excellent for wide-range of applications - ride n style.
