I'm trying to find a clipless system that I can use without hurting myself. While that sounds an odd statement, it's not so odd when I explain I'm severely toe out on the right foot. By severe, I mean the natural position of the foot is app 23 degrees turned out, as measured seated in a chair. Here's a photo of me standing.



I've added spacers to my platform pedals, moving them further from the crank. I wear a size 47 shoe.

I've tried, and failed, to use both SPDs and Shimano road pedals in the past - I was assured that I'd get used to the restricted position. Well, the SPDs kept me off the bike for a week after knee pain, and the Shimano road pedals I can't get into properly because it's an unnatural position for my foot.

I have a complicating problem in that I can't stand on the pedals to mount (long story), so I need to have the saddle lower than ideal. My right foot's natural position isn't with the ball over the spindle, but part of the arch. Forcing me to pedal with the ball of the right foot causes knee pain. (I'm dealing with uneven legs and a short left hamstring as well. How many riders have different pedals strokes for the right and left? )

I understand Speedplay Frogs are the usual suspect when it comes to lots of float, but I suspect I'll need to have the cleat angled to accomodate my stance. The only examples of severely toe out folks using clipless I've come across online both mentioned altering the shoe to allow an angled Speedplay plate - one fellow cut lugs off the bottom, another ground the slots a bit to allow it.

My questions are:

1. Are there an alternative to Frogs I should consider?
2. How difficult is it to angle the cleat on a shoe?
3. How difficult is it to alter the slots on the shoe to angle the cleat?
4. Am I stuck with platforms for life?
