I've seen some for sale on Evilbay, and searched with Google. IIRC there are many sizes. (I'll see if I can find a source ...

I would have thought, there would be at least one 'tip' expert here? I've tried walking distance in boots with plastic tips, and the tips don't last. [As girls keep telling me, high heeled shoes/boots are NOT walking attire!

I've recently had my 4" walking ankle boots re-tipped with steel. They seem to be lasting significantly longer, but they are noisey. Good for me in some respects as I love the 'clip-clop' sound, but they aren't discreet.
Long-term I need to find an inexpensive source of these tips, as paying £5/$10 a week for replacements, isn't realistic. Anyone?
