I have wide feet. GR9s and track pedals don't work for me. I use a comfortable pedal and am cognisant of my turns when riding fixed.

The most comfortable: MKS Sylvan Touring pedals with flip tabs, XL steel toe clips with sewn-on leather, VO leather toe straps
Close second: SR SP-11 (Lyotard Berthet copies - huge flip tab) with XL steel toe clips and VO Grand Cru leather straps. These new straps are the bees knees. The SP-11s have a ridge that accepts a slotted cleat, which is nice.
