Bought for my teenage son who has narrow heels and complained that his (expensive!) climbing shoes didn’t grip his heel properly and so were inhibiting his climbing. Did much research and found these recommended. First pair came and were slightly too small - he is a 7 in footwear so we normally go down half size in climbing shoes - next pair we ordered were half a size bigger than his normal street shoes and are perfect. The fit is superb and the heel is snug plus they are incredibly well made. I’m really pleased with them. He says they’re ’awesome’ which is fine praise indeed from a teenager!
