Have just made a big change from seven years of motion control run shoes to neutral ones. This was on the basis of video analysis with a top shop. The guy had me run in my old Structure Triax’s, pointed out how my ITBs and calves were working over time as the shoe was combating a pronation I don’t have.
I love the new shoes (NB 1023). The first thing I noticed is that I could actually feel the ground beneath my feet. The second thing was that it felt like running always used to when I was young. Didn’t up my volume but was flying already with a useful 10 mile race result.
Only problem is that three weeks in I was out on a run and I experienced discomfort deep in one calf quite low down. It wasn’t my achilles. I had to stop after 20 minutes. It didn’t tear or pull (I have know that sensation well enough in my calf!). Saw my regular therapist a few days later. She detected no muscle damage, nor loss of strength or flexibility. On that basis and my observation that the sole of that foot was experiencing some discomfort when biking plus the toes were cramping near the end of a swim, she thought that the posterior tibialis was irritated by the new position in found itself in the stance phase. She advised run little and often to get acclimitised.
A week on and I run every other day but can’t get beyond 20 minutes. Question is, how long to you persist in the acclimitisation phase? I am convinced the change of shoe is the right one and want to stick with it but not at the expense of being able to run at all.
Any advice out there?
Thanks in advance
Mark
