> I estimate I get more than a year out of my shoes (normally a few on the go at a time).
This is probably, though, because - as my wife regularly points out - I have:
1. the current pair of good redpoint shoes
2. the next pair of good redpoint shoes, bought in advance because I saw them on sale at a great price
3. the previous pair of good redpoint shoes, now used at the wall and for warm-ups (resoled)
4. the current pair of comfy multipitch shoes (resoled)
5. the current pair of good bouldering slippers
6 & 7. two older nearly worn out pairs of bouldering slippers.
8 & 9. two old knackered pairs of something or other that I never wear any more and should probably throw out.
The first seven all see regular use, so they last a lot longer than one pair for everything would. And iirc there's only one pair on the list that I paid anywhere near full price for.
(4. the current pair of comfy multipitch shoes aren't comfy enough so I need some others)
