You might want to look at the Shimano PD-T421 with CT5 shoes. The shoes utilize the recessed cleats. I st my shoe/cleat relationship a few degrees out from the centerline, i.e. the toe is pointing slightly out and my heel still clears the crank arm by about 1/2". This WAS my normal setting prior to the amputation. I can release by twisting my heel outward. I believe these pedals have about 6 degrees of float. The shoes are quite comfortable ride and walk in. Not the latest 'super-zoom' style but then againI'm not a slave to fashion. I've got a lot invested in the trike, Ice Sprint X, so I'll keep enjoying cycling on a reclined padded seat with three wheels. Take care...
