In reply to prestonclimbs_scotland:
I have a wide toe box and narrow heel and have been on a never ending search for the right shoe.
In general, lace ups have been the best for me as you can leave the front loose and really crank the tightness for the heel.
Unparallel shoes generally have a heel that fit me but the toe box is consistently too narrow. Scarpa shoes generally have a toe box that fit me but a very baggy heel.
Tenaya are similar to Unparallel, although the Mastia and indalo do fit nice on the toe but the heel is too baggy.
La sportiva have been my best fit so far, particularly the katana lace and genius, but both of these gave me pain on the big toe knuckle. Might be because I sized too tight? Might be a slightly too narrow toe box. They've been the only shoes I can actually heel hook with.
Whenever I've seen evolv or mad rock shoes in a shop, judging by the outline of the shoe alone, they look like they'd fit me the best. But whenever I've seen them I haven't had time to try them on, and they can be hard to find in the UK.
Anyway good luck, and let me know if you find something as I'm still hunting!
