I haven't tried them on rock and unfortunately never will. I'm a US 10 in street shoes and ordered the Bandits in US 9.5. Absolutely no way I could fit them in - they felt like US 6 or 7 something. Good price from Campsaver and good-looking shoes but sizing is off the chart. They don't retail higher sizes so I gave them to my daughter.
