Bamboo or wool for feet that sweat

Short answer: Bamboo moves moisture away from the skin fastest, while wool absorbs the most moisture before it feels wet. For closed shoes and long days, bamboo is the most common choice, but wool has its advantages, especially in winter.

Where the moisture goes

Bamboo viscose moves moisture out into the fabric and on to the air. Wool absorbs moisture inside the fibre and therefore feels dry for longer. The two materials handle the same sweat in different ways. Which feels better depends on the shoe and the season. See the styles in bamboo socks.

Wool can hold a lot of moisture

Wool can take up a lot of moisture before the fibre feels wet on the surface. That makes it comfortable on long days when you cannot change. On the other hand, wool dries slowly once it is damp. That matters little on a hike, but it matters if you need the same kind of sock the next day.

Closed shoes change the equation

In a closed shoe, moisture cannot evaporate, so it comes down to how much the fabric can absorb. Wool has an advantage there. Bamboo, on the other hand, dries faster afterwards when you take your shoes off. For everyday shoes, see bamboo socks for men and women.

Drying time between two days

Many socks follow a fixed rhythm: on in the morning, off in the evening and into the wash. Here it helps that bamboo dries quickly, because the socks are ready again after a night on the rack. Wool needs more time and often has to dry flat. With plenty of pairs, drying time matters less.

Comfort against the skin

Wool itches for some people, especially at the ankle and the top of the foot, where the skin is thin. Bamboo viscose rarely does, because the fibres are smooth and the fabric is soft. That is one reason many choose bamboo socks for men for the office and close fitting shoes.

Odour after a long day

Wool is known for smelling less after several days of wear. With a daily change, the difference between wool and bamboo is small, because the socks are washed anyway. Air your shoes between wears too, because a damp shoe smells whatever socks you have on.

Caring for your socks

Wash bamboo socks gently inside out and let them air dry. That way the cuff lasts longer and the heel wears less. Wool socks need a wool programme and should dry flat. Avoid the tumble dryer for both, because the heat wears the elastic and can make socks shrink more than expected.

Use both

You do not have to choose once and for all. Many people wear bamboo for everyday use, the office and work shoes, and wool for winter, the outdoors and long walks. That way you get the best of both materials. If your feet sweat a lot, changing socks at midday can also help.

Frequently asked questions

What smells least

Wool after several days of wear. With a daily change, the difference is small, because the socks are washed before the odour has time to settle in the fabric.

What is best for work shoes

Bamboo for most people, because it dries faster between two working days. The socks are ready again the next morning after a night on the rack.

Can you use both

Yes. Many people wear bamboo every day and wool for winter and the outdoors. That way the sock suits the day, and you get the best of both materials.
