Double Heel™
Two-part heel construction in trekking shoes. The part located under the heel ensures less strain on the leg muscles during long hikes. The part located closer to the toes ensures better control when descending.
3D Flex System Evo™
Technology used in the construction of the shoe's upper to protect the ankle joint from injury.
GORE-TEX® Performance Comfort
A versatile technology used in most trekking boots. It provides the boots with resistance to very adverse weather conditions. It is characterised by being waterproof, windproof and breathable.
Vibram® SpringLug Tech
This new technology consists of a rubber coating that offers superior protection and significant scratch resistance, as well as providing excellent grip. The low-density polyurethane content maximises comfort and also ensures that the sole adapts perfectly to uneven terrain.
HoneyComb Guard™
The hexagonal honeycomb structure creates a lightweight yet extremely durable protective layer. This design effectively absorbs impacts and reduces the risk of mechanical damage. It is ideal for demanding terrain, ensuring durability without adding weight.

    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.
