I'm a mens street shoe size of 11.5 My Katana's are a mens 9. For me, these are my high performance shoes. I strip them off at the bottom of each climb. That being said, I love the rubber, and the shoes inspire confidence. If you want something a little more plush, I'd recommend the mythos.

yes very good for all day. but with a more aggressive downturn your going to get some soild performance. really matters what your up to, if your doing long lines this would be a good one. but if your doing some seriously crazy biz a downturn would be good. the other thing to think is who you climb with. if your a belay whore and standing there in your shoes part of the time, this would be a good one. but if you rip off your shoes after every climb get a more aggressive downturn.

I have used these as a high end sport/trad shoe. Depending on how you size them will ultimately determine if they will be able to work all day. Ideally you want a shoe that will not be a cramped or aggressive style of fit, i.e. downturned toes, so that way you can wear them all day. All day comfort means in the end that you will be sacrificing performance no matter what.
