Technology

At La Sportiva we pride ourselves in developing the i nest products for the outdoors. We are always looking for

new technologies that help us improve our products. Through constant innovation we strive to push the limits of

our products to allow you to push your limits in the mountains. Lighter, faster, and stronger footwear developed

for you with passion. On these two pages we compiled some of the technologies we have developed and the

dei nitions of materials we put into our products so you can better understand and make informed decisions

about the products you choose.

SIZE CHART

MORE SIZES = BETTER FIT! La Sportiva shoes are built on European half sizes which are smaller increments than US half sizes. This gives us four extra sizes per

size run which gives you a better i t! MORE SIZES = BETTER FIT!

TECHNICAL FEATURES SYMBOL KEY

SUSPENSION SYSTEM

Integrated midsole/outsole construction based on four

important principles:

• maximum shock absorbency

• optimum comfort

• extreme lightness

• maximum performance

The suspension system provides stability while allowing

for protection, cushioning and traction. The midsole is

the layer between the outsole and the upper and is most

important for stability and cushioning in running shoes.

The outsole component contains the visible tread and

often in the case of mountain boots a hidden interior

dual-density AntiShock honeycomb grid Aircushion.

Gore-Tex ®

Schoeller ® Keprotec ®

A waterproof, breathable membrane used to line

shoes. Every Gore-Tex® shoe and boot is tested

for waterproofness and durability. Gore-Tex® has

variations of their lining to provide additional warmth

and additional comfort when needed.

A Schoeller® fabric made of Cordura,

Dynai l TS-70, Kevlar® and polyurethane.

MPE Outsole

Vibram ®

Stands for Mountain Performance Evolution. Made

by Skywalk with a dual density SBR design and SBR

air cushion.

The most trusted name in the shoe sole business.

Idro-Perwanger

Vibram ® XS Grip ®

Premium silicon-impregnated rough out leather.

Extremely water repellant yet breathable. The

best leather for alpinism.

The perfect balance of sticky, soft and hard

rubber qualities. The best rubber on the planet

that works over a wide range of temperatures.

FRI X ION ®

FriXion ® sticky rubbers are various sole compounds specii -

cally designed for mountain sports. FriXion ® rubber is custom

formulated for maximum performance for each intended sport.

For performance in any mountain sport, FriXion ® will give you

maximum stick and a noticeable performance advantage.

This innovative system uses a multi-directional upper hinge

that allows the ankle to take advantage of its natural

characteristics. The total freedom of movement of the ankle

allows using the boots l ex while rocking and transforming it

into pure power during the pushing phase. The upper l exes

following the movement of the foot, supporting it laterally on

steep and rough terrain and ensuring a stable hold. This allows

for a comfortable i t and even l ex after several hours of use.

FRIXION ® RS

Max-sticky compound for maximum rock

climbing performance.

FRIXION ® XF

Versatile, ultra-sticky approach shoe compound

for technical and rocky terrain.

WOMEN’S FIT

WOMEN’S

MEN’S

FRIXION ® AT

Soft, resilient and lightweight rubber, totally

non-marking, for road and trail. Exceptionally

wear and tear resistant.

La Sportiva ® utilizes a range of i ts

specially developed for the unique

shape of women’s feet, in order to offer

maximum comfort and to guarantee the

best performance. We have taken into

account that the female foot is much more

sensitive to pressure and has very precise

i t characteristics.

FRIXION ® XT

Used for dual compound soles. Optimum

combination of friction, wear and tear

resistance and shock absorption, that

combines AT and XF in specii c zones.

A) The forefoot has less

volume

B) The heel is narrower

and straighter

C) The calf is lower

IMPACT

P3 ®

A technical randing system developed to deliver power

to the sole and to maintain the down-turned shape of

the shoe. The randing system starts under the toes

and wraps around the whole foot. This maintains the

down-turned aggressive proi le of the shoe which

allows for better performance and power transmission

for the life of the shoe.

PERMANENT

POWER

PLATFORM

SYSTEM™

Our IBS soles are designed to reduce up to 20% of the

impact forces acting on the feet, legs and back with each

step while walking on hard ground. Due to the slanted and

opposing angles of the lugs shown in example A, the impact

forces are reduced as shown in examples B and C. The

opposing slanted lugs actually deform upon impact to absorb

20% of the shock imposed upon the feet, knees, hips and back.

In addition to decreasing the shock force upon the body

the inclined position of the tread pattern also offers a

superior grip on very steep terrain. The Impact Brake

System™ soles increase traction by 20% due to the

sculpted heel brake, offset lugs and the synergy with the

asymmetric axis of the foot as seen in example D. This

sole has been developed in collaboration with Vibram ® .
