I've been using platform pedals for almost 6 years now. All of my 3 bikes have platforms. I can wear any type of shoes I want. Clipless pedals are just a gimmick, absolutly unneccessary for daily commuting/errands.
I have even done a few 100 milers on my platforms with no problems. I just don't want to be attatched to my bike, I want to be free to get off my bike and walk or hike if I want to. Walking with cleated shoes is just stupid.
