Riviera Sandal Fleks On Fleks - Nightfall

The sky after sunset.

Nightfall captures the layered tones of the evening sky — deep charcoal, soft black, and subtle gray.

Sophisticated, versatile, and anything but basic.

Ready for wherever. Whenever.

Riviera was designed to be the pair you never have to think twice about. Two adjustable straps create a customizable fit while the clean, minimal silhouette works effortlessly with just about anything. From beach mornings to city afternoons, Riviera moves easily through the rhythm of your day.

Every Fleks style is built using proprietary Blumaka recycled foam, delivering the perfect balance of plush cushioning and supportive comfort — all while giving new life to materials that would otherwise go to waste.

Comfort that feels easy.
Style that goes anywhere. The sandal that fits your life.

THE FLEKS COMFORT SYSTEM

Just-right comfort.

Most casual footwear gets one thing right — softness.
But softness alone doesn’t support your foot.

At Fleks, we designed a system that delivers the balance your feet actually need: plush cushioning, natural support, and stable comfort that lasts all day.

Powered by Blumaka Recycled Foam

Every Fleks style is built using proprietary Blumaka recycled foam, giving new life to reclaimed performance foam from the athletic footwear industry. Instead of becoming waste, these materials are transformed into durable cushioning that feels great and holds up over time.

The Comfort Trifecta

At the core is our Signature Sculpted Midsole, designed around the three things your foot actually needs:

• Deep heel cup — helps keep your foot secure
• Sculpted arch support — encourages natural alignment
• Subtle toe bar — helps prevent forward slide

The result is footwear that feels soft when you step in, supportive when you move, and comfortable enough to wear all day.

Better materials. Less waste.

Our foam construction allows us to use up to 85% recycled material by volume, transforming performance foam scrap into long-lasting comfort. It’s a smarter way to make shoes — and a better way to feel good in them.

Fit note: Riviera features a unisex fit with adjustable straps. If you're between sizes, we recommend sizing down for the best overall fit.
