I did today's run with orthotics in my usual shoes, got to 6km & could feel blisters forming in the arches of both feet! This I do not need! I sat down, took the offending orthotics out of my shoes & finished the run comfortably without them.
Program : 12km @ AHR 82% Upper Aerobic Run.
At 6km having taken out the othortics from my shoes, I ran very comfortably without them for the return 6km. At home I looked at the damage & saw a very large blister on the inside arch of my good left foot & a smaller one, same place on my not good right foot! So there go the orthotics for now. I'm hoping the blisters will have gone by Sunday week. I've put blister block over both...tomorrow will tell if this temporarily fixes the problem.
