While cycling fashionists dismiss the venerable toe clip as obsolete, clips maintain at least one significant advantage over 'clipless' systems: that is, you don't have to buy special shoes in order to ride your bike. There is also one major corollary to this: riding a toe clip-equipped bike allows the rider to ride and, comfortably and for any appreciable distance, walk in the same shoes.
They are also, contrary to FUD, no more difficult to get out of than a clipless system, provided you don't tighten the strap while riding -- and most people don't.
