Upcycling instead of resource consumption and waste production
The shoe sole made of tire tread
Instead of a rubber sole made of a petroleum-based plastic, the Hennis sole is made of old, worn out tires which extends the product life and avoids additional waste. A seemingly worn-out or worthless item is re-purposed into a product with higher value. The shoe sole is designed for rapid acceleration and deceleration forces which adds to its exceptional wear resistance

The Vegetable Tanned Leather
As a natural product, the skin of an animal is always preferable to any plastic. It is not only protective and water repellent, but free from perfluorinated compounds that damage the environment. Throughout the world, leather tanning is done almost exclusively with chromium-III salts leading to significant environmental and health problems, especially in Third World countries and emerging markets. The process of vegetable tanning uses organic material and natural tannins derived from the barks, leaves and branches of trees and plants. Although the production time is significantly longer and the materials used are more expensive, the elimination of chemical laden waste water and harmful effects to our environment spares us the greater cost of tainting our precious, finite resources. The hides we use come from cows in Bavaria, the same place where the vegetable tanning takes place. Imperfections in the skin of the animal from scars, insects and horn injuries, are features of a healthy lifestyle that create a biologically, flawless leather. The fibers of the animal hide used for the leather are visible in the finished product, lending an authenticity and personality to the leather that makes it more unique.
Handcrafted instead of automated, repair instead of discard
The leather is not glued together, but elaborately sewn together by hand.Thus, the shoe can be repeatedly repaired for wear or damage. Only the outsole is glued instead of sewn because constant wear to the outermost layer would destroy the yarn.Because the shoes are manufactured in Portugal, they are subject to European production standards and limit resource consumption via shorter transportation routes.
