During my post op neuro physio sessions they picked up that I had a weak ankle and slightly turned out right foot so took the opportunity with my total loss of muscle memory to retrain that. I thought I would be OK on the bike as the re-alignment has certainly succeeded when I walk. My right foot is a lot straighter than it was pre-op. Problem seems to be when I am just using the ball of my foot, (as in correct positioning on the peddle) my heel turns inwards and fouls on the bottom cassette, not good as it means I cannot put equal pressure on both peddles. A bit useless when you are on the incline and need to keep a constant cadence up.

I am going to try the non captive toe guides that I used on the coast to coast ride. I had to swap the peddles out to accommodate them as they are bolted to the front and needed peddles to suit. The ones I chose have a reasonable serrated grip on them so it may be enough to keep my foot in line. I don't particularly want to go to captive clips or cleated shoes and peddles to match.
Falling off is not really a good idea with a repaired skull so I am hoping for an easy fix. I always wear a helmet but that does not make me bullet proof. The bike will be ideal for building up both muscle in my right calf and overall stamina so I hope I can get back to regular use.
