IMO, clips and straps and all of that stuff is a huge pain the you know what. Plus, I'm afraid that should I ever need to stop and put my foot out for balance quickly, or something like that, I won't be able to get my toes or shoes or feet out of whatever god forsaken contraption I've got them in.
Me, I just wear my Onitsuka Tigers (which I basically wear daily anyway) on a plain old flat pedals. Easy on. Easy off. Zero hassle. Comfy.
