I want to get a new pair of cycling shoes. I have a road bike but wondered it it matters if I wear Mt. Bike shoes. They have a rubber sole which makes it a tad easier to walk in if you should get off the bike to walk. I wonder it the road bike shoes would work better on a road bike. Also, what is a good feature to look for . I don't want to spend over $100. Just got the bike a month ago and have been using my Mt. Bike shoes that I have for spinning.
