I think it may be the cushioning that at fault with me, I to wear Thorlos socks but I'm going to try my 1000 milers tonight which I haven't tried with my new shoes.
It wasn't like this when I was a kid one pair of polyester socks used to keep me going for all activities, my feet smelt a bit but never burnt ho hum memory lane.
I'll let you know how I get on
