In reply to Jason123:
I've been in a similar situation to you. Was almost unable to climb due to pain in feet from rock shoes, so decided to try something different, accepting that my grade may drop but at least I would get some climbing in
Eventually I bought pair of Evolv Astroman, that are super-stiff and have been very comfortable - furthermore, my climbing grade went up!
I strongly recommend them - although agree with the vendor that it's worth trying on a pair - as the sizing wasn't exactly as I expected. Have climbed with them for 6 months or so now and have no complaints. Not quite as sensitive as usual rock slippers but no pain in toes.
