This has always been my point regarding the use of clipless. I can't afford to fall over and bust my hip or shoulder. I've done it (fallen) three times because of clipless. All were slow speed, weird little events but it got me thinking. I did some testing over a couple of years and compared my times over my weekly 9 mile route and found no discernible difference between clipless and plain BMX pedals and skater shoes. I suppose some might have a reason for clipless ( high bottom recumbents come to mind) as do racers, while actually racing, or maybe even riding constantly in the rain. But for the rest of us, a few tenths of a second is not a good reason to give up the convenience of being able to wear any shoe and get off the bike quickly and silently. With 'regular' pedals you never have to do any cleat maintenance or be concerned about cleats clacking on floors when the shoes wear. I know, I know, a whole bunch of you guys are into your hard soled shoes, coupled with those tiny surface area pedals and thats fine by me. I just haven't found the need to 'invest' in special shoes/pedals in order to ride my bicycle. This runs counter to what many people have been led to believe but seriously open your minds and do some personal testing over a long period. See if riding without being attached has some merit. You might find it liberating. Just keep in mind you have to use a pedal with a large surface area and a shoe that grips the traction pins.
