ReBOTL fabric This environmentally friendly fabric is made of RPET (recycled polyethylene terephthalate) textile fibre filament, created from recycled non-biodegradable PET plastic bottles. This material makes it possible to design products made with 50% recycled PET content in order to almost completely reduce the environmental impact of certain production processes. OrthoLite OrthoLite insoles offer great cushioning thanks to their compressed three-layer design that also improves the fit of the foot to the shoe. They are highly breathable, being made of polyurethane and manage moisture perfectly. They are also lightweight and can be put in the washing machine.
