In reply to D Berry:
The feel really stiff when you first get them, but they soften up nicely. But I would not say they have stretched too much over time. Even after getting resoled. I went 1/2 a UK size down from my katanas but I use the katanas for trad so they aren't fitted mega tight. The squamas fit really nice at that size for bouldering and sport. Once softened up they are decent for trad as well to be fair.
Really versatile. My go to shoe for almost all climbing over the last year. Although they didn't last long before needing resoled. 9 months. Suspect as that as I used them for everything tho.
