Quick answer:
Bamboo socks are the most effective material against foot odor. Bamboo viscose contains natural Bamboo Kun, which inhibits odor-causing bacteria — without chemical treatment that washes out. Synthetic socks make odor worse, cotton is neutral. Additionally important: change socks daily and let shoes air out for 24 hours.

Foot odor is not caused by sweat itself — sweat is odorless. The smell comes from bacteria that multiply in the moist environment between foot and sock. These bacteria break down sweat and skin cells, producing sulfur-containing compounds. That’s what smells.
The solution is not to sweat less (you can barely control that), but to deprive bacteria of their environment: reduce moisture and inhibit bacterial growth.
Bamboo viscose has two decisive advantages: it is naturally antibacterial (Bamboo Kun inhibits bacterial growth) and regulates moisture 3-4 times better than cotton. That means: less moisture + fewer bacteria = no odor. The antibacterial effect is permanent because it’s embedded in the material itself — it doesn’t wash out.
Combed cotton is better than synthetic because it absorbs moisture. But it releases moisture more slowly than bamboo and has no antibacterial properties. For normal sweating, cotton is sufficient. For heavy sweating or long days in closed shoes, bamboo is the better choice.
Polyester and nylon don’t transport moisture — they trap it. The result: a moist, warm environment where bacteria thrive. Exception: high-quality performance fibers like Coolmax, specifically developed for moisture transport.
Merino is odor-resistant and moisture-regulating. However, it scratches for some people, is more expensive than bamboo, and needs special care (wool wash cycle). A good choice for outdoor and winter, but bamboo is more practical for everyday use.
1. Switch to bamboo socks — naturally antibacterial, no chemicals.
2. Change socks daily — twice a day with heavy sweating.
3. Rotate shoes — never wear the same shoe two days in a row. 24 hours airing time.
4. Dry feet completely before putting socks on — especially between the toes.
5. If socks still smell after washing: wash once at 60°C with hygiene rinse, then switch to bamboo.
