Familiarity: I've used it several times
This boot will control something like a Madshus Glittertind or Atomic Rainier if you use a Voile 20mm riser plate and a Voile cable binding. The voile Riser pad and the cable pulling the ball of your foot firmly onto it will double your edging ability. You soon get used to walking in these boots, and if you are ski hunting or ski trapping or ski touring it will totally outclass plastic boots. If you want to turn fatter powder tele skis, then get a plastic boot. I have both kind of boots. Just choose the boot for the job at hand. A good buy at the sale price, but look at Fischer BCX 875 and Crispi Svartisen before you buy.
