In reply to DaveH70: Those are 5.10 Ascents and as you say they don't make them any more. I have two pairs at home which I save for long outdoor routes these days in order to avoid trashing them on stuff that I don't need the comfort for. Both have been resoled once by Cheshire Shoe Repairs with Stealth rubber, which has worked fine given that I keep them for comfort rather than precision.
I don't know of any other currently available rock shoes which have the heel pad of the Ascent, sorry.
From your photo I'd say that yours maybe just need a bit of a wash and, if they're wearing thin, a resole?
