I went for a fit the other day and we ended the session just as we began.
He measured my arch and then my feet and ended the session with: "your shoes are too small."
My first reaction: WTF? I'm a 10.5, the shoes are 44s. So I asked, is my arch is too far forward? His reply was a first for me: "No. Actually, you have short toes."
My size 44 shoes will not allow the cleat to be in the proper position relative to my foot (and short toes). I need a 46 instead. His answer makes complete sense as the only point where you are tied to your bike is at your feet and every other adjustment begins with that.
I have been suffering perpetual problems with my IT band, hip flexor, discomfort in the posterior of my knee and I shift in the saddle often. Slight adjusting of saddle height and fore/aft position never helped for more than a few weeks or so.
So, more comfy ride: yep. How about additional power? I hope so. Will my slightly slacking training schedule be saved by a few watts bought with a new pair of shoes and fit? (if I had a PT, I'd post real results--instead, circumstantial evidence must suffice.)
...stay tuned. I'm excited to find out.
btw, my fit has been rescheduled to the day before the first good race/crit of the season (for me). I don't know how much new shoes/cleat position will change the rest of my fit, so I have no reservations about racing at the moment though if it is "weird" I'll sit out. thoughts?
