FITTING ROCK SHOES


While it isn’t a black or white issue, a general rule dictates that soft shoes require a tighter fit, two to three sizes smaller than your street shoe size. We recommend you fit your trad shoes one to two sizes under your street shoe size. A thick midsole creates a platform on which you stand, while a slip-lasted slipper-type shoe relies on your crammed toes to create an edging platform.


Remember to factor in stretch. Unlined slip-lasted shoes tend to stretch a bit more than lined shoes -- about one full size. Lined shoes stretch about a half size. Remember: a well-fit comfortable shoe will work better than an ill-fitting tighter shoe.


La Sportiva's diverse last families have been specifically designed to conform to the widest possible range of both foot shape and climbing use. They constantly strive to revolutionize climbing shoe development and to provide every individual absolute freedom of choice in finding a shoe that is perfect for both their foot AND their climbing style.

FITTING HIKING/BACKPACKING AND MOUNTAIN BOOTS


To use La Sportiva's size chart to fit mountain boots, find your American size then go across to your European size, and then add one half size. When trying on boots make sure to bring the socks you would normally wear and any orthotics or custom footbeds you use.


Another note: La Sportiva's shoes are handmade, and you can experience minor variations in sizing from pair to pair in a given size. What you’re looking for is the size that 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. To check the length, you should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. The fit across the top of your arch is the single most important factor. If the lacing system here does not hold your foot in place, the boot will not be stable on your foot while you walk. If the boot is too short, your toes will get smashed walking down hill. Too long and your heel will slide up and down and give you blisters. Be patient, ask questions and make sure you’ve got the right size and the right fit and the right boot before you hit the trail.

HERE ARE A FEW TIPS TO MAKE SURE YOUR NEW BOOTS FIT PROPERLY:


*Try your boots on with the socks you intend to wear in the field.

*Try them on later in the day since feet are prone to swell slightly as a day progresses.

*Wear them only indoors 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.

*If your toes touch the front of the boot, most likely it is too short and you need the next half size up.

*Retain all original packaging which came with the boots until you are sure that you are happy with your purchase.


TECHNICAL INFORMATION

La Sportiva hiking, backpacking and mountain boots use only the best leathers available. They hand-craft our boots using old-world traditions and high-tech components to provide the finest technical outdoor footwear available. Most of their boots feature a one-piece leather upper which creates the highest level of water impermeability and durability. They use several different leathers created specifically for La Sportiva to meet the rigid design specifications for each model.


ANFIBIO (2.5-2.8 mm): Extremely water repellent full-grain leather with the grain layer, or top-grain, facing out. A special tanning process is used for optimal water resistance.


LORICA: A synthetic leather that is constructed from extremely small micro-fibers for a water-repellant, breathable and highly durable material.


IDRO-PERWANGER (2.8-3.2+ mm): This premium silicone impregnated rough-out leather is made for us by Perwanger Leather of Italy. Perwanger has been making leather in the Southern Tyrol region of Italy since 1780 and tans their Idro-Perwanger hides with a special process to make them extremely water repellent while still remaining breathable. This leather is the most durable available and is made from the corium, the strongest part of the leather.


NUBUCK (2.8-2.9 mm): Very supple and full-grain, the top-grain is micro-abraded for a soft finish of close fibered and water resisting leather. Because the grain layer is sanded, this leather accepts water repellent formulas very easily.



LEATHER (1.0-2.0 mm): Leather with a buffed surface in varying degrees of nap, from fine to coarse brushed. This leather is used in our rock shoes where sensitivity and breathability are most important.
