Grade: 1
Sustained blisters on the inner side of both feet near the heel; probable cause is the boots I was wearing which were a little too narrow for me; I kept walking for several hours after the pain began
8/30 blisters but there is little to no pain anymore
9/5 blisters finally collapsed while I slept; taking the weekend off and not walking probably helped as did taking it easier and not pushing myself to walk quite so fast
