I use to own a pair of Specialized mountain bike shoes (don't remember name of shoe) that I did not use on clipless pedals -- used toe straps and shoes. The Specialized soles were really stiff and I could walk around too! When I went clipless, I gave them to a friend who was looking for a stiff soled non-cleated shoe.

I am sure there are other brands of shoes that are good, but I really like Specialized ... I think they make an excellent product! I have tried other brands but always seem to end-up with Specialized on my feet!
