That's why it's important to say: SABOSPORTS don't use animal based materials at all. Only the artificial, including glues, threads, outsole components.
What we do use are:
* artificial leather
* synthetic suede
* synthetic mesh
* thermo elastoplast and its types
* synthetic laces
* metal eyelets and components
* man made foams
* only synthetic glues (no animal component included)
So in case it's important for you to use things with no animal based materials — take a look at SABOSPORTS shoes.
