no tree in the open country dies solely in the interest of organic tanning. On the contrary: the bark, which would otherwise be nothing more than waste from timber processing is put to good use. Think's all-natural, organically tanned leather is breathable, skin friendly, moisture absorbing, full bodied in structure, and free from harmful chemicals and toxins. Aluminum, chrome, mercury and the like are not added to organically tanned leather to make it easy care; Think! is highly apprehensive about such methods. This is why they leave their leather as natural as it is. None of the vegetable dyes contain heavy metals. And it goes without saying that Think! does not use synthetic inorganic chemical compounds or cheap carcinogenic coloring agents such as azo dyes. Organically tanned leather has no chemical additives. The animal skin is made durable by means of natural substances. This allows the leather to breathe and to absorb moisture naturally. It feels good and robust without additives such as chrome, pesticides, formaldehyde, and the like. To be sure nothing slips through the cracks, Think! has leather randomly tested by the laboratories of independent research institutes. After all, better to be safe than sorry. This fact is intangible to most but important to us. Thanks to short transportation distances, their raw leather does not have to be treated with chemicals to preserve it. Special salts and a proper cooling chain suffice. Few tanneries can produce organically tanned leather. Availability is very limited. The Think! philosophy rules out 95% of tanneries! A fact that has an effect on pricing. Organically-tanned leather is simply better but more cost intensive, slower and more complex to produce. In this day and age, vegetable tanned leather is an extravagance mastered by very few European tanneries. The result: a non-polluting product completely free of chemicals, exclusively produced in quality European tanneries with high environmental standards. Hypoallergenic, thus no harmful substances come into contact with your skin. Think!'s anatomically designed cork footbeds consist primarily of natural cork (which over time molds to the natural shape of your feet to create a custom fit) and natural rubber from the hevea tree.
