Just got these shoes and went off sizing recommendations. Found that going one whole size smaller is too much, or else your first few uses will be a bit painful. I would recommend going 1/2 size smaller (depending on how you like your fit). I am an 8-8.5 foot and think the 39 (not 38) would be the best sizing. I do not have a narrow foot and so did not find any issue with the heel being too loose. The rubber is very sticky and shoes are great for precision moves. Love the velcro flaps- makes it easy on/off and holds the fit extremely well. Wear these both crack and sport climbing. Most friends with these, however, prefer the shoes for the sport routes.

I love these shoes, I've been climbing in the women's Muira prior to these and I like this shoe just as well.

these shoes are great and stick to everything. however, i wear a size 10 street shoe (bought these in 40.5), have a bony ankles, and a narrow heel and cannot get them tight enough around the heel. the Velcro closure is great for the fit in the rest of the shoe. might be a better fit for larger (all around) feet. may be why also a hit with the men. awesome shoe, wish i could make them fit!

Just got these shoes after a lot of research for a new shoe and talking to a lot of other female climbers about their shoes. I normally wear a 7.5 (which is a little over a 38) shoe but got mine in size 37, based off of advice from others. Definitely go smaller on the size. They stretch out a bit but are super comfy so the small size is not as noticeable. I have used them in both the gym and outdoors and couldn't be happier. Highly recommend them!

Very good feeling for vertical and technical crags, also really enjoyable for bloudering. Pretty comfortable if you have large feet.

I discovered how toes were wonderful for climbing since I bought those shoes. I definitively increased my climbing level a bit from the moment I wore them. Many of my friends got them (or the Katana original (yellow)) I we are all very, very satisfied. And they feel like wearing house slippers! Precise on the toe, great adherence, feel like a lizard on a wall since I got them! I'll stay with La Sportiva for my next climbing shoes for sure.

This shoe is unbelievable. I have really narrow feet, so the women's katana is better than the unisex for heel hooking. Also, this is a great shoe for itsy bitsy little edges (the kind that might not actually exist except in your mind). One word of advice: get them smaller than you think you'll need. I wear a 41 or 42 (10 American) in regular street shoes and I got a 38 in these shoes. The 38.5 was too big. Believe me, the shoes are so comfortable, you can go WAY small.

I've used these shoes for several years now and I can't find a better all-around shoe. I use them for crack, slab, bouldering, steep climbing, techno—they are the best, most comfortable shoe I've ever owned. I can't seem to destroy them, so I keep resoling and climb, climb, climb.

I have narrow feet and low arches and for many years only climbed in Mythos. I've found that Katana and Tradmaster also work for me. I wear size 7.5 or 8 in street shoes, 8.5 in running sneakers, and 38 in mythos, 39.5 in tradmaster and 38 in katana. The katanas are not that comfy for wearing all day but they perform well.

I didn't really like these shoes because the heel was too big. I have a pretty small heel, and love the Mythos, but these just flopped around on my heel. The fit was good everywhere else with a 35 -- I normally wear a women's 36.5/37 in street shoes.

My street shoes size in at 9.5 (41??). I ordered both a 39 & 39.5. The 39's fit great now that they've stretched a bit and molded to my long narrow foot. They edge like a dream & yup they seem to stick to anything. I can't wear them too long, so am thankful for the quick velcro escape route -- tight velcro closure btw.

I'm currently on my third pair of Katanas and have nothing but praise for them. I wear a size 8 in street shoes and have found a 36.5 to fit comfortably (for climbing shoes). These shoes aren't synthetic, so you can expect a little stretch. I have wide feet for a women and, perhaps for this reason, I haven't experienced some of the problems with the heel cup that others have. I use these shoes for bouldering and rope climbing. I have a pair of larger, less aggressive shoes for long trad days when I might have to walk around in my shoes a lot. The rubber is super durable, but I've had problems with the buckles for the velcro closures before. Twice they have worn out before the rest of the shoe, which is a bit of a bummer. They are super expensive, but I think they are totally worth it. They're the only shoe I will trust on hard stuff.

I've been wearing the 5.10 coyotes and found they fit me like a glove. I wanted to try a bouldering shoe and got the katanas after reading all the nice reviews. So far it seems a pretty good shoe, and as others say, you may want to size down. I wear street 8 women's that fit me slightly loosely and I got the katanas in 38 for a really really tight fit and could have gone down to 37.5. I find the toe rubber a little thicker than I'm used to on the coyote, but I think my sensitivity will improve.The fit: my biggest issue is with the heel which is ever so slightly loose, even if I tighten the straps. This makes you feel a little unsure on heel hooks I think. The fabric seems to bulge out in a weird way both on the inner and outer heel. But this is really being picky, I think I am going to get used to it and this will be a good shoe.

I'm a newbie climber. This is my first pair of climbing shoes! It's worth the investment as opposed to spraying Lysol on those stinking rentals... *shudders* Once was enough for me! I climb twice a week so far the rubber isn't as worn out as i thought it would be.

Pros:
1.) Great on edging!
2.) Easy Velcro straps for resting your toesies in between climbing and belaying.
3.) Love the color <3
4.) Comfortable with my street shoes size 6.5 and i ordered a size 6.
5.) Sticky rubber ;)

Cons:
1.) Sucks at smearing :(
2.) Heel is too big on my feet, i would prefer it to be narrower.
3.) Too expensive!

These shoes are great. It took me a few days to get used to them...as it does any new pair of footwear, but once I did, they feel great. I definitely think my confidence in tiny footholds has increased with these shoes.

I wear an 8.5 in street shoes and when I tried these on at a local shop the guy only had a 38 and they're perfect....I don't do the whole way too small shoe thing either. A 38.5 would probably feel great too, but a 39 or 40 (which is what the size chart suggests) would be floppy.

I have chubby feet and high arches, and these shoes feel like they were made for me. I've worn them bouldering and sport climbing, and I never get blistery. They're super easy to get on and off, but I often just leave them on while I watch friends climb; they're comfortable enough to wear for hours.

Great shoe! No complaints. Amazing rubber and nice comfort even when fit correctly for a climbing shoe.
