So i'm onto my second pair of these trying to dial the fit in. I first got these in my street shoe size and they were extremely tight. could only stand to be in them for one route. after a few days of climbing I can keep them on for 2-3 routes max. I ordered the half size up and they are big enough they could be my next all day trad shoe if they stretch at all. seems to be a huge leap in volume for just a half size. Anway guess I have a new all day shoe now. If the smaller sizes stretches, the fit should be pretty good.
climbing performance has been great!
