Can this be done at all? After a year or so of using mtb spds on the road bike I decided to try SPD-SL. The left one feels great (as does the added stiffness of the road shoe soles) but my right foot cramps up quite easily as the cleat doesn't feel far enough back and feels too much like I'm on my toes. So is there any way I can get it further back (some kind of adapter plate?) without resorting to buying new shoes and hoping they go further back?
Could just go back to my mtb ones but they're a bit creaky and I prefer the stiffer soles of the roadie shoes.
