I rode with MTB pedals and shoes on my road bike for many years before going to road shoes and pedals. I still miss them at times. MTB shoes are so much easier to walk in and you don't have to worry about slipping and falling. I still change my pedals back to SPD when I'm taking my road bike on a tour where I'm on and off the bike and walking a lot during the day (ie RAGBRAI)
