I love these shoes. Their fit is nothing short of amazing. I have no problems with either the toe box or the heel. They are sensitive and sticky, they edge and smear great. The large velcro patch makes for easy adjustablity.
Great shoes.

I love these shoes. The rubber is plenty sticky, the toe box is downright comfortable! Velcro closures make it easier to get these on and off - I love them and will continue to purchase them. They didn't stretch too much at all for me. Size them kind of tight/comfortable.
I used mine for gym and outdoor climbing for over a year before i got a tiny little rip in the toe. take care of them, and they'll take care of you!

i love this shoe. i had the 5.10 mocisim before and this shoe what a difference a shoe can make. dont get me wrong i love my mocisims and they where i bit better for smearing but in every other way the katana beats it out its a great shoe and if it fits you well i definitely recomend it

I've owned my Katana's for almost a year now, and they've proven their worth many times over! Fits my foot like a glove, except in the toebox, but it's just a little chaffing on the top of my big toe and baby toe, on each foot. I can deal with that or tape my toes.

I was really concerned about the quality and stickiness of the rubber when I bought the Katana's, I'd only owned Five-Ten shoes with C4 rubber on them, so I'd had the best (at the time)...what about the rest? But the rubber on these surprised me! It's not as sticky but it's darn close. A little more durable too, they're not wearing as fast as either my Spires or Zlippers had, at the ball of the foot.

The heel area needs some time to acclimatize to it, it's different feeling that other shoes, feel's spacier and bulkier. But it's awesome for heel-hooking once you get used to it. Large contact patch of rubber there to use.

Edging is nice with them as well, they've got a good solid rand on them (if my terminology is correct), there's little flex in the front half of the shoe when you want it to be stable. However, when you want to curl your toes down and do some greater-than-vertical stuff, the shoe will bend into a concave soled shape quite easily (particularly when warm). Makes it a very good shoe for the more advanced technical stuff.

The fittings, the velcro, are sweet. Good and long just incase you have wider feet than mine, at least, and such a velcro patch! You can significantly adjust the fit of the shoe by putting the velcro down in a different area of the patch. If you want to pull the heel in more, pull the top velcro down lower on the patch, it'll yank the heel in tighter.

Price was the only thing that I didn't like...cost me $208 Canadian...though I've heard people around here buying them as low as $130 Canadian lately. Could have just been a one-off sale though.

I tried these on over the weekend thanks to a shoe a demo at the "New River Gorge Climbers Rendezvous". It needs to be sized small, like any high performance slipper. They're good shoes, but I felt the heel was too loose and baggy on my foot. The Katana's sister shoe, the Miura fits my foot like a glove. If you're looking for this kind of performance and find the Katana isn't quite right for you, try the Miura.
