rfg is now available online and at select retailers worldwide.
heritage brands like saucony® are partnering with bio-based performance brands like susterra® propylene glycol to support the shared mission of reducing the industry’s dependence on fossil fuels.
john hurban, vice president of global marketing and sales for covationbio™ pdo, said: “with saucony® we have a great partnership with triumph.
the partnership on rfg was a natural one as we aim to build a more circular economy with a renewable footprint globally, particularly in the performance footwear brand category. we are the world’s largest producer of 100% bio-based 1,3-propanediol (pdo). susterra® propylene glycol is a 100% pdo derived from regeneratively grown dent corn. our collaborations with primient and truterra support these regenerative agriculture methods on farms across the american midwest. we convert plant-based ingredients into key raw materials designed to reduce the need for petroleum ingredients and improve product performance.
“we are proud to be part of saucony®’s sustainability mission and this marks a milestone for susterra® propylene glycol.
this is the first example we know of using this percentage of bio-based ingredients in a sneaker midsole. we believe runners and fitness enthusiasts will benefit from the increased flexibility, comfort and durability of a performance shoe. this shoe stands out from the competition and goes further in terms of environmental footprint. ”
