FAQs

It’s not a treatment—it’s built into the shoe. 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.

*Though the waterproof layer could last for the entire lifecycle of the sneaker, it is subject to damages caused by accident, improper care such as machine washing (manual hand washing is recommended), negligence, excessive or abusive wear conditions, or normal wear and tear. However, our support channel is open to receiving requests on waterproof issues and will provide the appropriate support as possible.

Rens come with standard, medium-size width however the 4-way stretch material may be flexible enough to comfortably accommodate a slightly wider fit.

To clean your Rens:

For best results, use a standard sneaker cleaner made for synthetic athletic shoes or a mild/diluted laundry detergent and a clean cloth to wipe away any grime that won’t come off with a quick rinse.

As with all cleaning applications, test your product on a small, inconspicuous or unnoticeable area of the shoe to test for discoloration before applying it to the rest of the sneaker.

Methods to avoid:

We do not recommend the use of a washing machine to clean your Rens. The agitation of a washing machine may scuff or fray the knitted material or warp the internal waterproof membrane.

Additionally, avoid the use of dish soap as a cleaning agent as it may damage or degrade the upper material or internal membrane.
