i love them to death. they are so expensive (relatively), but work amazingly
i guarantee the problem will stop with them
make sure you tighten your boots..... and get custom footbeds.......
u should be fine other then that........
used to happen to me. from what i was told, when u smash ur toes in the front of your boots it creates small pockets under the toe nail where fungus can grow, and sweaty boots don't help. u can get some topical stuff from a doctor that kinda helps.
