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 4 out of 5 by from well worth it the quick lace system allows you to be able to wear the boot around town whilst not hiking meaning you don't get a sore ankle from it being super tight. when on the trails thou... it supports your ankle allowing for great stability and control over rocks, gravel, sand WHAT EVER! i was lucky enough to get these boots from a factory and had them resoled once when i wore the sole right out. since then i have bought the exact same pare and they've worn in just as good and just as quick. if you want a good boot and are a bit unsure as to what to go for OR you do want a good boot and know this is it well that what are you doing? this boot is great and will not dissapoint. ,,

Rated 4 out of 5 by from i would recommend this boot for anyone that requires a light boot that doesn't skimp on support I hike various rugged terrain, and need a boot that is affordable and can hold up to its fair share of abuse. these boots are by far the best light hiker i have ever worn. they are true to size and require no break in period. the toe box accommodates wide feet comfortably. they can handle a 25lb pack without any loss of stability. the heel support keeps the ankle secure while maintaining a full range of motion and the footbed can withstand a worthy amount of impact without any ankle trouble or discomfort. The vibram sole grips very well on most types of terrain and allows an impressive amount of stealthiness.

Rated 5 out of 5 by from The best boots ever I went climbing Mexico´s third bigest volcano and for a long story left my Alpinist boots at the hotel, but my gide suggested to take my Thunder boots, that he thought they will be "OK", after seen my options I decided to go on with my every day boots, we got to weather under 20 Fahrenheit with winds over 40 miles per hour and the boots were grate, I even got them wet at the glasear, and they kept dry, they and them selves very good with crampons, and in steep hills.,,Botom line they were asome, if I knew how good they were I would had bought them logn time ago.,,

Rated 5 out of 5 by from best like a beast i bought these boots about 2 months ago. from the second i put them on, i knew that they were the ones for me. i do alot of hiking and backpacking in rain and dry weather. the main thing is the gor-tex. picture yourself out on a hiker or just on a walk and you step in a puddle of water ankle high. what happens? your whole foot and sock gets wet. on my first hike, i stepted in puddles ankle high about 12 time. my socks in my boot were dry like the desert. they cover your ankle so you do not trist it and are very comfortable. i can't wait to get my next pair.

Rated 5 out of 5 by from These are very comfortable, practical boots that will make your feet do the happy dance! Okay, so I'm not wearing these boots myself...I bought them for my husband. He has owned several brands of boots, but his favorite is La Sportiva. The last pair, which were very similar to these, finally wore out after about 7 years; the sole detached. He tells me this pair is even more comfortable than those were. His feet stay warm and dry but not too hot, and he can hike, climb ladders, work in the yard and do all the 'honey do' tasks without getting any blisters. They were comfortable right out of the box.

Rated 5 out of 5 by from Great fit, no need to break in! I wear a 2A width and slipped these on and they fit! I usually have to wear two pair of thick socks to get hiking boots to fit, but these are like a glove! The top loop eyelet has a lock so you can pull tight and lock the lace in place before the top laces are done - great feature. They don't require any breaking in. Only problem I can forsee is that the bottoms are a little slicker and may not hold up on slicker surfaces. Will have to test to see!

Rated 5 out of 5 by from Great boot with no break-in required I wore this boot on my motorcycle trip to Alaska this year and I did close to 100 miles on the trails. I didn't have to break it in at all. The only complaint I have is that they are not waterproof at all...found that out when my 28 day trip included 26 days of rain. Maybe because I was riding a motorcycle at speeds up to 85mph, but even hiking they didn't resist any water.

Rated 4 out of 5 by from well made, solid, exactly what I was looking for I've been living in these boots for the past several days. After a long search for new hiking boots with good ankle support and a rigid feel, I took a chance on these. Your feet feel as though these boots are propelling you up hills. Downhill, you feel stabilized. Great traction and a great look too.
