Climbing shoe advice?

[juliet]

How long are climbing shoes supposed to last? I bought mine at the start of 2010, went climbing 2-3 times a week for the next couple of years, then had a kid, and have gone maybe at most once a month 2012-2017, and over the last 6 months am back up to once a week. I wondered today whether my feet feel a bit insecure because my shoes need replaced, rather than because I have lost my nerve. (I accept that better technique would also help, because it always does, right?)

They feel much much less grippy than the new ones in the shop, but I presume that's at least a bit normal...

Time to replace?
