A thin Vibram sole provides maximum ground contact while protecting the arch from rough terrain. Zero drop for a natural posture and stronger foot muscles.

Upper made from recycled materials and a low-impact manufacturing process. A design built to reduce the carbon footprint without compromising durability.

The airy weave promotes airflow and limits moisture, keeping your foot dry even during extended wear.

The Vibram sole offers reliable traction on dry or wet ground, in the city or on the trail.

Machine washable at 30°C, air dry. No special treatment needed to keep the shoe looking like new.

The KSO ECO is the FiveFingers model for anyone who wants minimalism without compromising on materials. Hemp upper, dye made from 100% natural pigments, soft and grippy sole: it's the most versatile model in the whole separated-toe lineup, the one you put on for the day without a second thought.

What hemp changes underfoot

Hemp doesn't behave like a synthetic mesh. It starts out denser, relaxes slightly after a few wears, then settles onto the shape of the foot. The result: a fit that becomes more precise over time instead of loosening. It also handles hot days better than a closed textile, without the plasticky feel. For light activities indoors and outdoors, it's the catalog's best compromise between natural material and ground feel.

This model or another

If you're after even more simplicity, the EL-X carries the thinnest sole in the lineup and slips on without lacing. If the eco angle is your main criterion, look at the Vi-B ECO, whose Ecostep Natural sole contains over 90% natural ingredients. The KSO ECO sits between the two: more structured than the EL-X, more versatile than the Vi-B ECO.

Which size to choose

The KSO ECO fits snugly, like all FiveFingers models. Measure your foot from heel to the tip of the big toe with your foot flat on the ground, and check it against our size guide. If you're between two sizes, go up: a compressed toe cancels out the whole benefit of the five-toe construction. The model is available in 5 sizes, 37 to 41, in men's barefoot shoes.

Frequently asked questions

Does hemp hold up in the rain?

Hemp absorbs water and then dries quickly, but this isn't a waterproof model. For wet terrain, look at a model with drainage.

Can it be washed?

Hand wash in lukewarm water, air dry, never a tumble dryer or radiator. Direct heat warps the sole.

Is it suitable for running?

It's designed for versatile use and light activities. For regular running, a dedicated running model will suit you better.

Comfortable and lightweight, good product for light use. The natural color is nice but a bit plain.
