Legs that don't match

Hi all. I have one leg that is about 1/2 longer than the other. I can't
quite decide whether to order a bike (I'm looking seriously at the folding
BikeFriday) with two different length cranks, or not. I ride a recumbent
exercise bike every day and find it comfortable, but in order for it to feel
right, one of my feet ends up contacting the pedals (there are straps on the
pedals that do not restrict front to back foot position) in a different spot
than the other foot.



Any thoughts on this?
