I can't add much except to say that I tried them on at the last PSA conference I attended, 3 yrs ago in Chicago. I really liked them, and probably would have bought a pair except that I needed a 1/4 size smaller blade than on my current boots. I was looking for another pair, not a replacement, and I didn't want to deal with two sizes of blades. I'm going to Conference again in May, and I may just switch this time. They were super comfy even with the heat molding, and I felt they were very snug.
