SPD vs Speedplay Frogs
It is time for new shoes and I am considering a switch from SPD cleats to Speedplay Frogs. It seems that every few years my body must change a little causing my knees to stress and requiring an adjustment on the SPD cleats to get the centering spot where I need it. The slightest tension away from center causes discomfort on the tandem. Never a problem on the half bike.
So, who out there has made this switch and is there a learning curve? Is the walk-ability similar? Do the frogs wear out from walking?
