I have used a pair for 2 winters now, approx 50 days of use.
Pros: Good support
Easy to lace on
Sole has not cracked (yet)
Cons: not even water resistant, never mind water proof. Feet are wet after about 15 min of skiing through wet snow.
Cold - not much insulation. Too narrow for a heavy sock.
Too narrow, one width does not fit all. Lots of abrasion on toes and ankles.
Eyelet pulled out 2nd day of use.
After skiing through wet spring snow for 10 min my feet start to get damp, after and hour they are soaked (I'm wearing full length gaiters).
The 'one width fits all' does not work for wide feet.
Iv'e some Sorrel Thinsulate light weight boots for snowshoeing that I can put on after a night out at 0 deg f and my feet will stay warm - not so with the Alpina's - skis seem to suck the heat out thru the bottoms.
One of the eyelets came out after about 20 hours of use.
