I recently had cause to remove the (worn) tips from a pair of boots.
Much to my disappointment the tips were so tight in their respective tubes, the tube left the heel when I tried to (gently) see-saw the tip out of the tube. The locking pin that goes deep inside the heel came out too. These pins were plain (thin) bar.
I had no problem getting the tubes back in the heels, with pins opening up the (split) tubes, and locking them back in place.
I'm no cobbler, more of an engineer. I'd have had no problem using araldite to keep the tubes back in place if necessary. In fact I almost dropped a blob of the stuff inside the heels before the tubes were inserted, in an attempt to lock the tubes in permanently. But they felt fairly secure without additional bonding.
As long as the tip end of the tube can expand for a new tip to be inserted, I can't see there being a problem?
Having re-read the original post, I'd suggest someone has fitted the wrong size tip? It costs £5 around here for a pair to be replaced, money well spent if it saves the heels from further problems? Seems to be a bit of risky solution being discussed here, in what I would be tempted to call a "bodge"
Get the right sized tips fitted? Losing a tip while walking on asphalt could ruin the heel on a shoe, and I doubt Timpson's keep replacement 5" stiletto heels in stock, if at all.
