Where should I stop for foot care at C&O Canal 100?

Fit the shoe with room for swelling, pretape the spots that have blistered on you before, keep grit out, and change socks at every stop you have access to. Blisters come from pressure, friction, and moisture, so remove whichever one this course hands you the most of.
