Dual sided Frogs, ? any SPD shoe with a bit of tread cut away..
around the cleat "knobs"..

or a roadie shoe, that you cannot walk in..

did you know? that with spare Cleats and a pair of Winwood Decksters ,
you could even turn your Speedplay Frogs into a pedal you can ride in normal shoes.
the cleat screws into an aluminum plate, and you fit it on one side of the pedal.
then you have that side for the regular shoes..
