I have a set of Shimano XTR clipless pedals and love them.And no I have not fell as of yet I have had them for about 6 month's.The only thing I don't like is the cost of shoes that part suck's.Clipping in and out is easy I think I had no trouble using them at all.But I went back to my toe clips.The reason was my feet was killing me with my shoes I use three different pair and all hurt like crap.With my toe clips I wear my reg shoes and no pain for me.
