Standard Specifications

Sole Revolution is produced from recycled high-performance athletic shoe rubber. Materials throughout the sporting goods industry are subject to and routinely tested against stringent consumer safety standards. If it’s worn on your body, it’s designed to be safe. But because SPS decided long ago to put human and environmental safety FIRST on our list of priorities, we use additional layers of process control and transparency. Whether using California Prop 65 or EU toy safety standards (EN 71-3) as your benchmark, Sole Revolution passes with ease.

We regularly test for “Polycyclic Aromatic Hydrocarbons” (PAHs) like anthracene, napthalene, chrysene, fluorine and pyrene, especially those classified by the EPA as a “probable human carcinogens.” We also test for 17 heavy metals like arsenic, chromium, lead, mercury, cadmium and zinc. Test results are compared to California OEHHA Soil-Screening guidelines based on total exposure (inhalation, ingestion and dermal absorption in a “residential scenario”).

Sole Revolution allows your community to meet YOUR environmental and human safety requirements, not just the minimum sports surface standards out there.
