Rens Size Chart
Rens fit true to size for most customers. If you have wide feet or are between sizes, we suggest you size up.
How To Measure
Set your heel against the wall on the piece of paper.
Draw the outline of your toes.
Measure the distance from the back of the paper to your big toe.
Repeat on other foot and go get the shoes that hug your feet just right.
Softer than eating a marshmallow on a feather bed.
Effortless style meets lightweight comfort. Minimalistic design, ultralight outsoles, and knit construction all add up to a serene sneaker experience. Heavy on features but feather-light on your feet.
Footwear that fears no forecast. A coffee infused liner creates an impermeable seal that remains incredibly breathable.
Rens in the wild
Does the waterproof feature wear off?
It’s not a treatment—it’s built that way. Each pair of Rens contains a breathable, waterproof nano-layer driven by our AquaScreen Tech™. This keeps your feet stay dry for your sneaker’s entire lifecycle.
Are Rens really 100% vegan?
Yes, all materials, dyes, and adhesives are 100% vegan! No animals were harmed in the making of these awesome sneakers.
Why use Coffee to make sneakers?
Food waste is a leading driver of greenhouse gas emissions. Did you know that the world consumes nearly 2.5 billion cups of coffee every day?
We can’t solve the problem of coffee waste alone, but we can show the world how this material can be used to make awesome products.
Do you offer wide sizes?
Rens come with standard, medium-size width however the 4-way stretch material may be flexible enough to comfortably accommodate a slightly wider fit.
How should I clean my Rens?
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.
