Gave in an ‘bought’ a copy on Google Play. £11, but no protractor!
Already paid for itself. I couldn’t shift a pain in my right foot which started early in rides and would last the whole ride. Had tried an aaaaawful lot of fixes including wider shoes, looser straps, shims/insoles etc.
Turns out my foot was ‘waterfalling’ i.e. the cleat was too far to the inside of the shoe and the outside of my foot was taking extra pressure where it stuck out of the edge of the pedal. Shimming the pedal out the way and moving the cleat back to the centre of the shoe the corresponding amount *seems* to have solved it.
Annoyingly I had always suspected this but had figured that modern stiff shoes wouldn’t suffer for their position over the pedal. I’d even experimented with moving the cleat etc. but obviously hadn’t moved it enough. Buying the book at least confirmed I was on the right track.
I find Steven Hogg’s website excellent as well, had convinced me to fiddle with shims to adjust for differing leg lengths, intial results seem promising (I realised I was pedalling with my left heel down, but right toe down, I also noticed when pedalling I was never looking straight down onto the wheel, basically never riding with the bike perfectly upright!).
