The Shoes are another part of the picture.. I got the Shoes for using the regular type road pedal modified .
to optimize the positioning, ease of rotation of foot, 'float' on the pedal. and the usefulness off the bike, walking.
to that end, sole, built up, to leave the gap for a hourglass slot for the back plate of the pedal .
More comfortable ergonomic insole added, ( Birkenstock has cork composite 3/4 length ones I like)
and a toe clip that holds the strap open , but the strap itself stiff enough to remain round, and so easy
to get the smooth sole sliding easily , into the opening, quickly and easily..
Its been a fine combination.. there Were 'touring shoes' with sole texture that were reasonable to walk in
comfortable to pedal in ... Italian, French & British shoe companies but not well distributed outside ,
as I found, of bigger European cities ,
then phased out by now.. happened to see a few , 15 + years ago , on tour , there..
