Plastic tips, less than a week.
Metal tips, 2-3 weeks. But hard to know for sure, as I sometimes wear my wedges. If I'm going somewhere local, I tend to wear the wedges because discretion is needed, the stiletto's when I want to listen to the clip-clop of the heels and don't have to worry about being seen. These walks currently take place after dark, though this is already becoming increasingly difficult.
I usually walk on asphalt footpaths. Last week I gave paved footpaths a go, and damaged the heel covering on a pair of heels with them continuously getting caught in the cracks or gaps between the slabs.
Asphalt is as we know, designed to provide grip to vehicle tyres. It's not smooth, and on footpaths, it's certainly not even. [Tree root growth being the main problem, with Sky cable laying being almost as bad.] The asphalt attracts fewer
sudden changes in height than paving slab finishes, so it also attracts fewer claims from people who suffer falls and trips. No surprise then, it's the covering of choice where I live.
I'd love to find some way of walking around carpeted or wood floors, a mile each night.

Block-heeled boots seem a less expensive solution, but I'm shopping at the wrong time of year. So eBay is getting a lot more attention from me, than it should be getting. Hey-ho, roll on Autumn.
