obviously the concept of stop and go urban riding is lost on some of you. clipless pedals are great for bike-only type fitness rides. but if you are running errands in the city and want to walk around road shoes are worthless. now, moving on to a constructive answer. you need a flat soled shoe with a sticky rubber tread and a narrow profile, especially if you are also going to use toeclips. indoor soccer shoes are an excellent choice. but my favorite are actually adidas superstars (70s lowtop basketball shoes!!)with the big rubber shell toe. they are durable, comfy, super grippy and work well with toeclips. traditional cushy runnng shoes are probably not a good choice. padded skateshoes would be fine on a bmx platform but too bulky for clips. so lets review
indoor soccer shoes, good.
superstars, very good.
running shoes, bad!!
skate shoes, not as bad.
ps, shimano also makes a rubber soled touring shoe with a recessed cut out for a spd cleat. these would probably work very well with toeclips and are definitely walkable and will have the stiff sole you are looking for.
