Originally I bought these $165 cross-country ski boots on sale. Worn no more than 5 times, I now offer them for $70. They are immaculate. These size 12 (or Euro size 46.5) Merrill's are very sturdy.
For 3 seasons I have attempted to ski in size 12 boots... which is not my size (I'm a 10 1/2 - 11). Each time after one try I gave up for the season. It was a very bad idea. Too big for me, they may be perfect for you. I just bought my correct size, and that's what I should have done in the first place.
Rotefella "step-in" Back Country ski bindings require specialised boots. This pair is made by Merrill, and are warm and well-designed.
