Keeps your shoes as fresh as a summer breeze
Hey, sometimes shoes smell but the secret is: yours don’t have to. Rens coffee-yarn is naturally odor-absorbent, kills odor-causing bacteria for your shoe’s entire life-cycle and offers 3x more odor control than standard textiles. These shoes will always stay as fresh as you do.
NOT JUST BETTER FOR YOUR FEET.
BETTER FOR YOUR ENVIRONMENT.
The world’s second favorite beverage, 23 million tons of organic waste produced by the coffee industry every year. Every pair of Rens diverts 300 grams of methane-producing coffee waste (SCGs) from landfills and recycles over 6 plastic bottles (PET).
HOW do you make a coffee sneaker?
These materials are fused with a low-heat, low-water process to create the yarn used in every stitch of fabric on our sneaker.
Combined with minimalist, single-seam design that uses fewer resources to give you a greener, more durable sneaker.
Coffee brings the features. Recycled plastic brings the flex and durability.
Both combine to create a sneaker built for your environment.
