La Sportiva footwear is built and offered on European half sizes, which are smaller increments than US half sizes. This gives them four extra sizes per size run, and ultimately gives you a better fit.

Please review La Sportiva's size conversion chart above to help determine your ideal size. Below you will find additional information about how to fit and break in the different styles of La Sportiva footwear, which will also help guide you to the correct size.

• As a general rule soft shoes like climbing shoes require a tighter fit, or about two to three sizes smaller than your street shoe size.
• La Sportiva recommends you fit your trad climbing shoes one to two sizes under your street shoe size.
• La Sportiva offers a lot of lasts, and each offers a different fit and feel. Remember to factor in potential stretching.
• Unlined slip-lasted shoes tend to stretch a bit more than lined shoes, or about one full size.
• Lined shoes stretch about a half size.

• PERFORMANCE FIT - offers a high performance fit and a downturned last.
• TECH FIT - a more technical fit and a last with neutral profile.
• COMFORT FIT - a comfortable fit and a last with more volume and a neutral profile.

• Find your US Size in the guide above, then find the Euro Size conversion and add one half size.
• The ideal size holds your toes ever so slightly away from the front of the boot while the lacing system is snug across the top of your arch.
• If you can try to boots on beforehand, make sure you wear the same size and weight socks you would typically wear with the boots, and any orthotics or custom footbeds you use.
• It is ideal to fit boots later in the day since feet are prone to swell slightly as a day progresses.
• Wear your boots indoors only until you are confident about the fit.
• Your foot should feel snug (not tight) from the arch back into the heel pocket with just a minimum lift as you walk. If your heel lifts make sure the lacing is snug and not too loose.
• Your toes should NOT touch the front of the boot, but when you kick the toe into the floor, you should know where the front of the boot is. You want just enough room to wiggle your toes.
• If your toes or sides of your feet feel squished, most likely the width is too narrow and the boot will not work for you.
• If your toes touch the front of the boot, most likely it is too short and you need the next half size up.
• Make sure to keep all original packaging that came with your boots until you are sure that you are happy with your purchase.

Rated 5 out of 5 by from Great Mountaineering Boot! These boots are fantastic. I wanted a pair of uninsulated mountaineering boots for some alpine style climbing this summer and La Sportiva came through. The boots are comfortable out of the box but I replaced the felt insoles with a pair Superfeet Green insoles and recommend folks do the same. I have put over 100 mi on them under a heavy load and over non-technical terrain to break them in. They have great support, a rigid sole, are 100% waterproof, and allow my feet to breath. I wear a size 13 and ordered a 47 and they fit perfectly with a little extra room in the toe box for front-pointing or kicking in steps. I am excited to strap crampons to them and really see what they are capable of.

Rated 5 out of 5 by from like wearing a rhino combined with a cheetah on your foot. This boot ROCKS! I have hiked over 100 miles in my pair and they seam barely worn and are cozy when its cold, dry when its soggy and comfy throughout. In buying such a stout boot I was worried about getting blisters yet haven't had one yet after 4 different week long trips and a handful of shorter ones. Including one through a good amount of snow in Never Summer Wilderness, yet toes were still toasty and dry. More support than an armchair for your feet, and these boots make you crave to go farther always.,,

Rated 5 out of 5 by from Killer Boot I work on a well drilling rig where I'm completely soaked head to toe all day and these boots hold up great! They are extremely tough, comfortable, and provide plenty of support. I get traction on slick metal which came as a supprise because I was warned they would do great for some things and not so great for others. But so far iam extremely happy with them. Iam looking forward to a cold winter to see how they hold up. I got a half size larger than recommended because I was told it helps with breaking them in (which it did). Hope this review helps!

Rated 4 out of 5 by from This is my 3rd pair I've now rebought this boot a number of times as it seems to be the best boot for me that is out there that isn't outrageously expensive. This is one of the few boots offered in a size 48, so my options are really slim. But this boot fits really well and lasts a long time. I do with the waterproofing would be better, but I doubt any boot can stand up to the wet Pacific Northwest snow.

Rated 5 out of 5 by from Great Boot! I prefer La Sportiva Mountaineering boots, and this boot is no exception. I look forward to bagging a few peaks with it this summer. I also plan on hiking some of the Colorado Trail.

I need the Karakorum in a 47. I saw them here before, but now it seems to be the only size not listed. Can I order a 47?

Asked by: ZachAttack
Hey there, Thanks for the question. Unfortunately if a size is not listed as available on the website, we are not able to order it. The inventory on the site reflects everything we have available in our warehouse, stores and via special order from the manufacturer. Once that's available again, it will be listed in the size drop-down.
