Amazing Shoe

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Purchased: 42

These were my first pair of climbing shoes that I bought from
Backcountry and I can say for a fact that I have no regrets in making my decision. I bought a .5 (half) size smaller than my normal size and after a month of use, they have formed into the perfect fit. You can rest easy knowing that your toe hook, heel hook and smears are secured with these on. The P3 technology has kept the aggressiveness of the shoe in top shape. These are by far my favorite pair thus far and I'm pretty sure I'll be getting myself another pair in the future.

I am looking at the katana lace. I have 46 tc pros and 45 futuras. I am wondering what size for a more sport/aggressive fit? Anyone know


I've sized these the same as my other La Sportiva bouldering shoes, and been happy. I suggest sticking with the same size as your Futuras, as they are a pretty similar fit. This will curve your foot less than the Futuras (but way more than the TC pros). So, it's possible you could be happy with a 44.5, but I think 45 is the best first guess.

With that said, I will get you a return shipping label, if you think the 44.5 would be better.

I'm looking at the katana lace as a potential shoe for multi pitching. My current shoe is an evolve shaman in a US8/EUR41. I wear a 7.5/8 in street shoes (typically vans and Adidas respectively). I was wondering what size I should order for a comfortable but snug fit for extended use.

Best Answer

i use these for multipitch and I went down a half size since it will expand a bit. After 2 weeks, they were comfortable but not too loose. I wear a 10.5 street shoe and got a 10 (or the EU equivalent of a 10).

Will there be any 40.5s, 41s arriving soon?


We have a bunch of 40.5's and 41's coming into stock soon. Would you like me to watch inventory on that for you?

Shoot me an email anytime you have questions!

Sure, thanks!

Will they be in before the sale ends?

I currently have Mythos. Should I buy the same size as my Mythos (which have really settled down and are comfortable for me) ?

Best Answer

Hey Welshguy,

I would get the same size, but expect the shoe to feel much different than the fit of the mythos. These are more aggressive and asymmetrical so they are going to feel a little smaller than the mythos in the same size. Also these will not stretch as much as the mythos do.

If you want to talk more about sizing or try on a few different sizes please contact me at the info below and I would be happy to help you out.

I wear size 12 street shoe I had a pair in 44.5 and they were very aggressive fit for me. Its unfortunate the toe rubber chipped on the first slab climb I made. been waiting almost 4 weeks for La Spotiva to get back with me about warranty. Probably will not buy another sportiva shoe because of this hassle on warranty.. they run small

Thanks Wes & Dan. My issue is that I have hobbit feet (wide) and take 44's in Mythos. They have stretched and fit really well now but I'm after a more aggressive shoe for edging and small toe holes. Lace-ups are what I want so that I can finely adjust the fit. Maybe a 45 would be better since the stretch in these shoes are a lot less than mythos ? Realistically I think I need to demo these shoes before committing to buy.

my Katana laces did not stretch at all. but be ware I think they have delaminating issues of rubber. and warranty well thats another topic. I replaced my katana laces with the tenaya tarifa drop one size for comfy tight fit or 1.5 for agressive

Stiff, sticky, and stuffy...

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Height: 5' 11"
    Weight: 162 lbs
    Size Purchased: 44.0 the good sense of the words...
The 'Permanent Power Platform' create some underfoot stiffness that feels like they take some of the stress off your big toe when you're edging in a desperate stance. They feel really sticky and promote a ton of confidence when you're smearing on tiny crystals and featureless faces. I ordered a half size larger than I normally would have to make them a little more comfortable in when jamming the cracks, and they perform wonderfully in that setting as well. The slightly roomier than aggressive fit makes them my go to trad aggressive shoe. For steeply overhanging routes I would be happy with the same shoe, but a half size down from the ones I own.

My only gripe and the reason for a knocking off a star is that because of the moderate downturn, they do start to wear my feet out on slab after a couple of pitches.

I only wear these outside and they have been wearing as expected, but I will definitely need to resole them more quickly than the harder Onyx rubber on my 5.10s..

Great shoe!

  • Familiarity: I've used it several times
  • Fit: True to size

I bought the Katana for moderate bouldering and more technical climbing.. I have a more comfortable mythos shoe for splitter cracks and easier climbs. These are great edging shoes and stick to the tiniest crystals and slickest faces! Took about 10 pitches to break in to the shape of my foot, but didn't really stretch considerably. True to size.

Any idea when you will be getting these in sizes 42 and up?


We should be getting a shipment in the next few weeks here. I'll do my best to let you know once they come in.


Are 44.5 or 45 gonna be in stock soon?


We have a bunch of 44.5's and 45's that should be arriving shortly. Let me know if you'd like me to watch that for you and let you know when they get to us?

I wear an 8 in street shoes (nike, adidas) and a 9.5 in rental shoes (so with socks). what size should i get in these?

Best Answer

Go a full size down from your street shoe. I wear a 10.5 (Vans, Nike) and I use a 9.5 for a tight but comfortable fit. For a performance (toe crushing fit) go down 1.5 sizes. Never wear socks with your climbing shoes, it's akin to wearing a life vest with your surfboard.

Spot on Zach - definitely like the life vest with a surf board analogy, could not be more true with wearing socks in climbing shoes.

Any idea when you might get size 43.5 - 44 in? Is there anyway of sending a notification when they do?

Hey Joseph T.

Thanks for your question. It looks like we have both of those sizes on order to come in mid-August. We have quite a few coming in so check back on the site then!

Let us know if you have any other questions!

Good all around.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Height: 5' 8"
    Weight: 135 lbs
    Size Purchased: 38.5

I found these to be pretty versatile, for a sport shoe. They are a pretty stiff shoe, which gives you a solid platform when you are trying to balance on small edges, which I was very grateful for. They smeared just fine, as well, which is a plus. Also, they are one of the most comfortable down-turned shoes I have ever tried.

I wear a 38.5 in most La Sportiva shoes. My street shoe is 8.5-9.0. Techincally, I could go to a 37.5, but it's just too painful for me. The 38.5 in these was just right.

Questions? Hit me up!

Are there any plans to restock the bigger sizes? NOBODY seems to carry anything bigger than a 43 and I heard something about a Dock Worker's strike, but that seems to have ended. I bought a pair of 44.5s and loved them but had to give them up because they were too painful. Wanted to get a 45.5 or 46 but they've been out of stock for about 4 months....

Best Answer

We do have a few 45 and 45.5 on order. I would imagine they wouldn't take long but I cant make any guarantees. Wouldn't hurt to chat with one of the gearheads and leave them your info so they can follow up with you if they find anything.

Next Step up from Mythos

  • Familiarity: I've used it once or twice and have initial impressions
  • Height: 5' 8"
    Weight: 200 lbs

Was really interested in this shoe, Ive owned the Mythos for years and want to get something a touch more aggressive. This is it. Edges better than my Mythos but, it really tackles some overhung moves a lot better. A lot stiffer than the Solution so it edges a bit better, still smears like a champ.

Size 43 in all of La Sportiva's mountaineering boots, 41.5 in the Mythos, tried these in a 42 and they were perfect. They were a demo pair so, they were pre stretched out. I would have to break them in a bit if they were new but definitely the 42 would be for me. If I was tackling harder routes the 41.5 might be an option just make sure its a tight fit but, at my climbing level I appreciate a bit more comfort.

Can you recommend a size? My mythos are 41.5 and my street shoes are 9.5-10

I wear a US size 9 street shoe and these in a 41 and they fit like a nice painful glove with optimum edging power. I would say sticking with 41.5 would be a wise choice!

How much will these shoes stretch, because I have one foot that is a half size smaller than the other. Also I wear like a 44.5 in the evolv pontas II does anyone know what that would equate to in the katanas?

Trevor what is your street shoe size and how tight do you like them. I do not see how they will stretch much in length but maybe just on top of shoe where your toe knuckles are

Are you planning to get 42.5 any time soon?

I have a pair I'm trying to sell. Email me at They are 42.5. Cheers, Zach

When will you have 42.5 in stock? I bought the 42, but am unsure if they are the right fit. I am a women's 10-11 but wear a 42 in my mythos.

Thank you!

I have a pair of 42.5 I can sell you. I bought the wrong size and need to buy another pair. I'll sell for 140 free shipping. Reply with email, or I can with mine. Cheers!

Best Answer

Zach, not sure how to email but are those 42.5 still available?
