What aspects affect how much a climbing shoes stretches? I have heard leather stretches and synthetic doesn't but which bit of the shoes is actually stretching?
My old Scarpa Vapour apparently leather upper and took about 3 months for those to be even close to comfortable plus a session in a hot bath (no idea if that made any difference just glad the colour didn't run!)
I think the new ones are synthetic so if you make the switch would it be wise to upsize by half thinking I might not get that "give" that made the old ones tolerable
Always ended up with indent marks on top of my big toe after 20mins or so (this was going just 1/2 down from my street shoes.
Failing that anyone got ideas for a narrow foot bouldering shoe with 2 velcro or laces and a good toe rand to toe hooks (happy to go womens fit)
