Banana Socks: Powerful Odor Control × Eco-Friendly Innovation

Worried about foot odor in situations like these?

• When taking off your shoes at a traditional Japanese restaurant

• When visiting a friend’s home

• The moment you take off your leather shoes after wearing them all day

The solution to these everyday concerns comes from an unexpected source…

BANANAS.

■ Powerful Odor Control — Evidence

◇ Adsorbs & Decomposes Odor-Causing Compounds

The inner yarn of the socks—the part that comes into direct contact with your skin—contains a special fiber designed to adsorb and decompose unpleasant odor compounds, including ammonia, acetic acid, and isovaleric acid.

It delivers such powerful deodorizing performance that even when a red ammonia solution is sprayed onto the material, the odor disappears almost immediately.

◇ The Naturally Porous Structure of Banana Fiber

Banana fiber has a naturally porous structure, giving it excellent moisture absorption and moisture-wicking properties.

This helps reduce stuffiness inside your shoes and provides a drier, fresher feel compared with ordinary socks.

■ A More Sustainable Choice — Social Good

After bananas are harvested, large quantities of the stems are discarded.

The disposal of these agricultural by-products can contribute to environmental concerns such as CO₂ emissions, methane generation, and soil pollution.

Our Banana Socks make effective use of these otherwise discarded banana fibers.

Simply by wearing them, you can make a small contribution to reducing environmental waste while enjoying a comfortable pair of socks.

■ Designed for Comfort — Product

Banana fiber is naturally firm and can sometimes feel slightly rough against the skin.

To solve this, YUI carefully blends:

Banana Fiber × Cotton × Acrylic

This carefully balanced blend helps reduce the roughness of banana fiber while preserving its distinctive dry, fresh feel.

■ Designed to Fit

We use highly elastic yarn to create a comfortable one-size-fits-most design for 23–28 cm (US Women’s approx. 6–10 / US Men’s approx. 5–10).

※ We recommend washing the socks once before wearing them.

The socks may shrink slightly when air-dried in the shade. This is a normal characteristic of the material and helps create a closer, more comfortable fit.

■ A Design You’ll Want to Wear Every Day

Featuring a simple double-line design that works effortlessly with a wide range of outfits and occasions.

Subtle yet distinctive, it adds a touch of personality to your everyday look without being overly bold.
