frogs, mounted neutral will do: 0 heel in, 26 heel out.
quite frankly it's a limitation of the pedal design. if the pedal binding mech could be rotated or reversed, then it would be amazing.
Right, but there is no reason whatsoever to mount them "neutral". Mount them turned a few degrees and you can pivot your foot inward more than enough to heel-strike the crank. How much more inward float can you use?
