Cramp outer edge of foot (sole)

Can’t see your post and can’t

Can’t see your post and can’t view source on this device, but I got really bad cramp on the outside edge of my soles on both feet when I tried cycling shoes. 

Tried Giro spd shoes with flat pedals and suffered a bit but as soon as I tried clipless pedals, the cramp came on after less than 10 miles and I had trouble walking for a few minutes after each ride. Tried road and MTB shoes and pedal combinations and tried cleat wedges and insoles but nothing relieved it. Gave up and went back to flats and trainers.

Hope this is at least a bit relevant to your post!
