For two years I've been wearing Alpina Tibet, no problems, no blisters, nothing has fallen off yet despite at least 25 two-thousanders per year and many hills in between. Expecting another year. Got La Sportiva shoe of similar weight for free this year, which fits my foot less well, so next shoe from Alpina too. Plus supporting our producer, which counts for something, right? Also have 20-year-old Alpina winter shoe for automatic crampons, still wear occasionally, probably not as comfortable as today's. Calm blood and nice mountains!
