Versatile. Grippy. A True All-Arounder.

Flex handles daily walks, active days, and changing conditions with ease.

It’s built with a 10.5mm sole: natural rubber for grip, EVA for shock absorption, and a sturdy black canvas footbed for all-weather reliability.

Flexible, durable, and ready for anything - Flex is our go-to for maximum grip.

New to Barefoot? It might be your sandal.

If you're just getting into minimalist footwear, Flex is a great entry point.

Your feet might need time to adjust - barefoot walking strengthens muscles and brings you back to a more natural way of moving.

Flex gives a solid mix of ground feel and protection, with just enough cushioning for rough paths and long days. You’ll feel connected, without feeling unprotected.

Barefoot Running

Flex is our top pick for barefoot running, from roads to trails.

The slightly cushioned sole absorbs impact and eases pressure on your feet, while the grippy canvas keeps you steady, even when things get sweaty.

It’s built for distance, connection, and performance - mile after mile.

Water Performance

Flex holds up when things get wet - whether you're crossing streams, paddling, or cliff-jumping.

The textured canvas footbed keeps you steady, even when soaked, giving you full confidence anywhere you go.

ZuZu Flex

I have been into barefoot running for a long time, but have never tried sandals until now. The ZuZu Flex are amazing. I love the grip and the ease in which they fit to your feet. I would recommend them to any runner out there.

love em!

What I like most about these is the recycled tyre soles...but also love the feeling of running with feet open to the air and the cushioning is perfect for the rocky/flinty paths where I live. Very pleased with them. I think I would like slightly wider straps...having seen some earth runner straps... but that might just be a grass is greener thing.

Love the flex

I just received them and they fit really well. It is almost you have nothing on your feet. I think this is gonna be the only “shoe” I need this summer 🤩🥰

Care Instructions

To keep your sandals with you for the long run, it’s best to avoid prolonged exposure to direct sunlight or high heat (like inside a closed car). That can damage the materials and lead to faster wear.

If dirt or dust builds up, it’s recommended to gently wash them with lukewarm water and soap, using a brush or on a delicate wash cycle (up to 30°C).

To prevent odor, make sure to dry the sandals well after each wash or water adventure - preferably under direct sunlight until fully dry, and don’t leave them wet and unventilated for too long.
