Built with a trail runner in mind for comfort, the compression molded EVA midsole with TPU inserts provides the cushion needed to eat up mile after mile in the great outdoors.

The whole boot is fully synthetic, made from AirMesh, Nano-Cell™ direct injection and PU leather upper that is abrasion-resistant and tough against the dirt and rocks you'll evidently come in contact with. Completed with a Vibram® Nano outsole with Impact Brake System™, you'll start and stop your way up the mountain with smooth ease.

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 Super light I wore these literally right out of the box on steep (up and down) rocky/uneven terrain and not a single blister. My big concerns were support and that the soles would not be rugged enough. They certainly do not give the support of a more heavy duty boot, but they were definitely adequate for my 210 pounds and 35 pound pack. Regarding the soles...they were phenomenal. I barely felt a thing beneath my feet. The light weight was a little disorienting at first (almost high stepping) but they felt great after half day. A bit narrow so may be tough if you have wide Hobbit feet.

Rated 3 out of 5 by from Not to good a product This are like my 8th La Sportiva boots, and they are a definitely upsetting product of the brand La Sportiva, they are not very good matirial, they slip form almost all surfaces, you can not even belive that the sole is Vibram. They are light, but you can feel even a small rock on your feet, defenetly I will never buy this product again, and made me think about La Sportiva quality. I have used them just once or twice a month and in easy terrain, they look old, ripped, and not what you paid for. Tanks to this boots, now I am trying new brands and not just La Sportiva like I used to buy for almost 6 years.
