WOMAN FIT, shapes specifically developed for the female foot anatomy, comfortable and enveloping provide comfort and stability when walking on mountain trails with uneven ground.


Elica is an exclusive AKU system that integrates the last – insole – midsole – tread, tracing the anatomical shape of the sole of the foot.
It has been certified that the Elica technology promotes comfort, reduces impact with the ground and effort when walking.

The GORE-TEX® membrane contains approximately 1.4 billion microscopic pores per square centimetre. These pores prevent water droplets from penetrating the membrane, and water vapour, i.e. sweat in gaseous form, from escaping easily.

Vibram is synonymous with the sole for mountain footwear, an essential component for the safety and technical performance of the product.
