dear robbiedob,
they're called straps, not strap ons. a strap on is a sex toy, usually worn by a woman to make it seem as if she has a penis. a strap, in this context, keeps the foot secured by eliminating lateral motion and is to be used with a clip. also, we don't like your cranks. not even a little. and: please don't say schnazzy. it's not a real word.
