With some diffidence and not a little trepidation, I'll raise my tiny hand and say "Please Sir."
Although toeclips are pretty well obsolete, I always understood they were best fitted with a gap between toe and toeclip, their only purpose being to hold the toe strap in place. This does, of course, imply the use of shoe plates, so I'll clip-clop off for my tea.
Anyway +1 to that post and a bit of humour usually makes stuff a lot easier to read.
