Shorter crankarm length might help.
dparm said:I went with speed play pedals, which have an MTB and a road variant, and this allows some float and motion in the shoe. I also added a washer to one pedal to get it out a bit.
Speedplay actually makes longer axles for their road pedals, but I believe ONLY in the stainless steel material, and not their titanium, or chromoly axle materials.
As far as I know, they are one of the only pedal manufacturers who even offer this as an option. ()
I know since I have the absolute longest stainless axles they make to help keep my size 13 shoe's heel cup from clipping the chainstay on my Merlin Road's frame.
