I found these boots fantastic for giving me that extra 'edge' on harder routes. However, they were utter agony and contorted my poor feet into the most un-natural state. Some say this is necessary for a technical boot but I was literally crying after doing a short second pitch after standing about belaying my leader from a small ledge in the blazing sun (feet swelled). So if you can stand the agony and the deformed feet they are a brilliant shoe, as for me I can't!
