Being rough on my shoes I have found these to hold up much better than the various 5.10's and sportivas I have owned over the years. They are nice and comfortable for being sized tight. (I am generally a 11.5 in street shoes... wear a 10.5 in moccasyms and 43.5 in katanas and a 10.5 in the Inti) They are quite flexible... like slipper flexible but with a much better toe. Based on the durability, comfort, and performance these are a solid shoe for beginners and experienced climbers alike.
I hadn't heard a whole lot about Tenaya, but took a chance at my local shop. They fit well when I tried them on, and they still fit well. They don't breath very well, so my feet get a little swampy here in the south, but I've never been dying to take them off my feet. They fit pretty true to street size, in my experience. The rubber has worn pretty evenly, even though I have sloppy footwork. The downturn is between slight and moderate. My only gripe is that the metal loops for the straps have actually started rusting, but I attribute that to being overly sweaty and the fact that this is the wettest summer we've had in Atlanta in a long time.
