I put those on my commuter... just so I could switch back and forth as needed. The one odd thing about them is they seem "sticky," they do not rotate as easily as other pedals I have used. I can't help but wonder if they really are "dragging."
As far as a good concept... I love them. I wear spds and can walk in them when I need to, and if I am just running to the store, I just wear my sneakers... the concept is great.
