I got back into trail running after Christmas as a knee injury kept me off the bike. I took it steady, but ended up clocking between 50 and 70k a week. Nothing longer than 40k. No issues with feet. I'm an army officer, and haven't had a single blister in 8 years of running around in boots.
I went away with work and could only run once a week. Since I've come back I have started again, and my feet are falling apart.
Distance not extreme (couple of 10-20k runs a week) in the same shoes (pretty new, not tight, comfortable Salomon's). Same socks, similar terrain.
Every run I have a black toe, a blister in-between a toe, blister under my forefoot, blisters under my bloody toe.
I can't even get a climbing shoe on anymore! It's now becoming the limiting factor in my running.
Any ideas?
