HappyFlops fit best with a little extra room. If you have a half size (e.g., 24.5 cm), always choose the next size up. Our complete size chart is on every product page. Measure your foot from heel to toe in centimeters for the best match.

From 100% EVA material: lightweight, waterproof, non-slip, and skin-friendly. Our production facility is ISO 9001 certified and inspected by SGS, so you can be sure you're getting quality in your home.

Yes. Thanks to the EVA material, they are 100% waterproof and perfect for the bathroom, pool, or beach. Just rinse with water and they are as good as new.

Simple: rinse with lukewarm water and a little mild soap if needed. For stubborn stains, use a soft cloth or brush. No washing machine, dryer, or harsh cleaning agents – that is not necessary and can damage the EVA material.

Many of our customers wear HappyFlops precisely because of the 4.5 cm thick, shock-absorbing EVA sole. That cushioning relieves pressure with every step and supports a natural posture. We are not a medical device, but fewer than 0.5% of our buyers return their HappyFlops. That says enough.

With normal use, HappyFlops last for years. The EVA material is wear-resistant, colorfast, and does not deform easily. If you do experience a defect due to a manufacturing fault within the factory warranty period, email us and we will arrange a replacement pair.
