Ohhh, those were my first choice boots when they first came out. Unfortunately, I had to switch for Scarpas because of the price. I would be interested to read comments on them as well...so light !
Here's one review I found. This is IMO some interesting technology. I tried on and bought a pair a couple of days ago. I'll let you know how they work when Mother Nature cooperates. First impressions are that they are light and flexible and definitely A hybrid design between Plastic and Leather.They are actually a Kevlar Composite Shell. Should be interesting...I'll be the guy with the Orange footware this Winter.
