Water poured on Rens sneaker to check, waterproof

100% waterproof

Footwear that fears no forecast. A coffee infused liner creates an impermeable seal that remains incredibly breathable.


Shoes that stay as fresh as you do. Naturally odor-absorbant and antibacterial coffee yarn eliminates odors for the shoe’s entire life-cycle.


Changing the shoe game with upcycled materials. Used coffee grounds combine with recycled plastic for a footwear material that is both durable and sustainable.

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 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.

Can I request a refund for my pre-order?

Yes! You can request a full refund of your purchase at any point during the pre-order campaign. If at any time you need to cancel your order, simply send us an email to and we will be happy to provide you with a full refund.
Note: Refund requests will result in you losing your place in the pre-order campaign.

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.

Tens are the most comfortable shoes ever!

It’s like wearing slippers - easy to slip on and walk miles with cushioned support. Plus the ‘stealth black’ looks cool.

Renz sneakers

My sneakers are waterproof, tested by me in the snow. They feel perfect for all kinds of use. I like that they are not to cold to wear, as Norway is a cold country. If/ when I buy a new pair, I would try some nice colours, - and half a size bigger. Thanx!

Love it! No smell and truly water-proofed

I tried it for a week on different occasions: hiking, zipline , business meeting. I got to say that I love Rens.

Stealth black sneakers

Intially they were tight around my toes but having worn for a few days they have eased up and are more comfortable. The fit now is very good considering i have narrow feet and typically i need lace ups. Very happy so far
