Impact Brake System
Innovative La Sportiva brand technology applied to the sole of mountain boots for walking shock reduction, traction support and improved ground grip. The unique placement of the tabs ensures maximum impact absorption.
GORE-TEX® Extended Comfort
A technology used in shoes designed primarily for intense activity in warmer weather. Provides maximum water resistance. The shoe is devoid of an insulating layer, which increases breathability and moisture wicking.
OrthoLite® Hybrid
OrthoLite® foam, which has less impact on the environment. Its formula combines 5% recycled rubber and 15% foam from production waste. OrthoLite® Hybrid was therefore created from 20% environmentally friendly materials, but retains excellent cushioning properties and uncompromised performance.
Vibram® Megagrip
Vibram® Megagrip® rubber provides exceptional grip on wet and dry surfaces, combining excellent traction with high abrasion resistance. Thanks to its balanced flexibility and grip, it performs well on varied terrain, even in conditions requiring precision and stability. It is a reliable solution for those navigating difficult terrain and variable weather conditions.

    Super grip

    Very well made and comfortable. Used for more than half a year in Polish mountains and lowlands. Made about 300 km and not even one foot abrasion. The only drawback for me was the high cutout and my right ankle felt it a bit at first. Used heel pads and the problem disappeared. On rocks it holds, on wet grass and in mud too. Waterproofing not yet tested. If they are on promotion then the price is acceptable too.

    Comfortable and quality in line.

    Because of my wide feet I was worried that the size would not fit my feet. But I'm on my second pad and it's very comfortable, durable and very water resistant. I didn't even have to break it in. I love it.

    How to measure the length of your foot - instructions in 4 steps

    1. Prepare a sheet of paper and set it on a hard, non-slippery surface - it is best to tape it to the floor.

    2 Stand barefoot on a piece of paper - distribute your body weight evenly and set your foot straight.

    3. Mark the tip of the big toe and the back of the heel - preferably holding the pencil vertically.

    4. Take off the foot and measure the distance between the marks - this is the length of the foot. Repeat for the other foot and choose a larger measurement, matching it to the size chart.
