I tried on the kaylands last night, and they would destroy my feet. I was worried I would get blisters in the 5 minutes I had them on. The transitions between the heel cup and the ankle was very severe and too low, it dug into my heel like a miner in a gold rush.
The salomons on the other hand were quite comfy, one of the best I have tried on; though I have yet to talk to anyone with a "report from the field".
