Had a pair of the Alpina prior model of these 3 pin type backcountry boots. The fit was perfect, they were comfortable. Great waterproofing and they were fine until they were involved in a flooded garage mess that made them mildewed and covered with mold. I was sick when I had to trash them. I used them for 4 years of nordic patrolling as a volunteer for the NPS and was thrilled every time I laced them up. The sole was awesome and grippy for walking when out of the bindings. I loved them.

Weight if you ever try them for faster classic parallell crosscountry instead of baclcountry trails. I tried them a few times doing classic style with my vintage 3 pin skis and could tell a difference.
