as well as its impact on health
All manufactures are made with high quality leathers and respectful dyes for skin and body.
The uppers are made with very flexible, soft, adaptable and strong vegetable tanned leathers, natural colour (non dyed or finished to be hand-dyed and finished later) , so they are chemicals and heavy metals (like chrome) free.
Uppers are made with ecological vegetable tanned calf leather from ECOPELL company (*with the exception of open styles like sandals and ballerinas).
The German company has a long tradition on best quality ecological vegetable tanning leathers. ECOPELL leathers comes from free-range animals and the tanning process is made with natural materials. They have the VEGETAL TANNING CERTIFICATE CHROME FREE as well as other important certificates confirming the high quality of their products.
This ecological leather comes from free-range cows that graze on German grasses, what gives high flexibility, strength and warmth to the leather. It is also really breathable because its natural processes that don´t close the pore.
The natural animal husbandry creates the possibility of having some imperfections in the leather like insect stings, horn marks...demonstrating his natural life. All that marks are sign of a quality and natural animal life.
Those features made this leather perfect for preventing allergies and damaging chemical products.
*Open styles uppers are made from vegetable goat leather chrome free and natural color (non dyed or finished in factory). This leather is selected for functionality reasons because open styles need an special stiffness and strength on cuts, so the high softness and flexibility of the ecological calf leather is not appropriate on these cases.
There are two kind of soles:
Cowhide leather sole is around 3.5mm thickness, it has good adaptability, flexibility and allows Earth connection: Earthing / Grounding. Low grip and low abrasion resistance
We should be aware that leather is a natural material that needs some care and maintenance. Also, it is not recommended to be used on wet surfaces , so it can slip and damage leather after prolonged use on those surfaces.
Rubber sole can be used over wet surfaces without slipping and harm the material. It doesn't need any care or maintenance. Rubber sole is not conductive, so it doesn’t allow Earth connection.
You can choose between the regular rubber sole (crepeline) 3mm thickness or the Vibram Tank (Morflex) sole 4.5mm thickness.
Rubber sole 3mm thickness (crepeline) It is really light and flexible, as well as the ground feel is amazing. Medium grip and medium abrasion resistance.
Vibram Tank sole 4.5mm thickness (morflex) It is a bit more stiffer than the regular rubber sole but is still very flexible and has a good ground feeling. High grip and high abrasion resistance.
Leather is only dyed on the outer side (grain), so dyes are not in contact with skin. The inner side (suede, in contact with skin) is natural, without dyes, therefore, it can’t fade or leak dye or causes allergic reactions or makes the skin to absorbs harmful chemicals.
Dyes used are Low Volatile Organic Compound (Low V.O.C), so they are no toxic for skin and body, and are respectful with environment.
