Keeps your feet dry in any weather
100% Waterproof. Footwear that fears no forecast. Stay dry on the move no matter where life takes you with breathable comfort.
POWERED BY AQUASCREEN NANO TECH™
Our innovative waterproof technology contains micro-perforations that allow air and water vapor to pass while offering complete protection from water penetration. By fully submerging the fabric in water, you can see how each one of those bubbles is a little breath of fresh air for your feet.
We start with post-industrial plastic and used coffee grounds to create a workhorse material that can carry you anywhere. Our coffee knit provides a personalized fit designed to hug your foot and conform to your natural movement.
AquaScreen Nano Tech™ lets air in, keeps water out and stops odor-causing bacteria in its tracks. Stop skipping puddles and start aiming for them.
Our removable insoles are constructed with a full-recycled sockliner and a unique blend of performance EVA and memory foam for all-day support and comfort.
Built with an ultralight and flexible midsole to provide advanced impact-resistance and responsive cushioning for even the most active lifestyles.
FEELS LIKE WALKING ON Marshmallow
Effortless style meets lightweight comfort. A minimalistic design, ultralight midsole, and knit construction all add up to a serene sneaker experience. Heavy on features but feather-light on your feet.
MADE FOR YOU & OUR PLANET
Designed to be earth-friendly and feet-friendly. Rens fuse used coffee grounds and recycled plastic bottles to create a lightweight, long-lasting sneaker while reducing waste and increasing comfort.
ODOR-CONTROL
Rens’ unique coffee material traps odors and fights the little monsters that make them. Our innovative fiber contains tiny micro-pockets that trap unpleasant odors and inhibit the growth of odor-causing bacteria.
Yes, all materials, dyes, and adhesives are 100% vegan! No animals were harmed in the making of these awesome sneakers.
You can return your order within 30 days after receiving the product. The product can be returned either for a refund or an exchange. In order to make a return, the product must be in new and unworn condition, with all tags attached and the original packaging contents enclosed in the original box. We reserve the right to reject any returns, requests for exchanges or refunds if the item does not meet the above requirements.
Rens come with standard, medium-size width however the 4-way stretch material may be flexible enough to comfortably accommodate a slightly wider fit.
We recommend using a small amount of any standard, non-solvent based detergent, and a clean cloth to wipe away any grime that won’t come off with a quick rinse.
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.
