Stream leather is tanned using vegetable extracts and ground tree bark. In order to fully take in its qualities, it has been churned non-stop for several weeks inside a special cylinder. It is greased in a slow and delicate process, by expert hands in an enterely artisan fashion, using natural animal fat and olive and sunflower oils. Once it is dry, the outer coat of the leather is minutely impregnated with olive oil. This operation provides the shoes with an exclusive finish that naturally protects them from water, dirt, and the passage of time.

Using 100% natural rubber insoles is a key factor in achieving shoe flexibility and durability. Natural rubber bends easily and absorbs impact, but completely recovers its shape and thickness and is more durable than synthetic materials. This results in comfortable, resistant and extremely long-lasting soles. Also, once natural rubber is discarded it degrades much more rapidly than synthetic materials. Nature always assimilates more easily what she originally created.

Our comfort lasts have an angled outline that adapts to the natural shape of the foot. By studying the foot's anatomical configuration, we created lasts that will replicate our physical contours. The models that incorporate this ergonomic shape do not compress, either while walking or in repose, making them incredibly comfortable; and in this case comfort equals health.

The latest technology in breathable materials - Our insoles utilize a recycled carbon compound that optimises the relationship between shock-absorption and breathability. The result is a level of performance that is superior to that of other materials. Some models also incorporate an anti-bacterial finish to provide optimum foot hygiene.

These anatomically-designed insoles are made from recycled cork. Their shape is simple yet extremely important: they fit the contours of the foot like a glove.
