dear anyone. Having a bit of a mare training for 100km in that my feet come out in red hives when doing anything over 12 miles. I do wear very lightweight boots and have tried a variety of socks but nothing seems to help. I am now doing over this every weekend and having real difficulties. My event is on 25th/26th May london2brighton, any advice? Socks with wool, without wool etc?! I have spent a bomb on socks but can not seem to find any that do not cause the rash etc...any advice would be greatly received!
