Feet roll out because knees are out - the V-twin

I had a customer come in recently with some really big feet (size 15.5). Anyway when this guy pedals, his knees flare way out to the sides and it appears that the weight distribution on his cleats is far greater on the lateral side and limited by the Sidi shoe itself. So when he pedals his feet want to roll to the outside and that of course pulls his knees out.

First you address the stance width – move the cleat "in" to move the foot out. (this is even before wedging or rotation)
Since he has Look Delta I am guessing you install his pedals with a pedal wrench and not an allen key. He probably needs a much wider stance width so you can add a 20mm pedal spacer.

Keep in mind the more V-twin or bow legged one rides/pedals the chances are you need to add another wedge – thick to the inside.

Most of the pressure is on the outside since he is pedaling with knees out and not straight up and down.

Goal – move the foot out and under the knee – if the knee is still out after moving the cleat and adding a 20mm spacer. Add a varus wedge in addition to his current needs.

One last comment

The cyclist’s knees go where they want to go. The goal is put the foot underneath the knee. It is not the big feet that is pulling the knee out. The knee is out because the feet are too narrow for this cyclist.
