Bamboo socks for trainers and why the material matters most there
Short answer: A trainer with a rubber sole and synthetic lining shuts the air out. There the material of the sock is the only thing that can move moisture away from the foot.
The shoe cannot breathe
A closed trainer holds onto moisture whatever the manufacturer writes. That is why the sock is the only layer that can do anything about it. See bamboo trainer socks for men.
Bamboo moves the moisture
Bamboo viscose absorbs moisture quickly and passes it on. The foot stays drier, and dry feet smell less, because bacteria need moisture.
The length in a trainer
An ankle sock ends just above the shoe edge and does not chafe. A footie disappears into the shoe when you walk far. See bamboo footies for men.
Change shoes and air them
Two pairs of shoes worn alternately dry fully in between. That does more for the smell than any sock can. See also all bamboo socks for men.
Frequently asked questions
Do bamboo socks help against smelly trainers?
Yes, partly. They keep the foot drier, but the shoe also has to be allowed to dry between wears.
Which sock length for trainers?
An ankle sock ending just above the shoe edge. It barely shows and does not slip down.
Why do the shoes smell and not the socks?
Because the socks get washed and the shoes do not. Alternate between two pairs of shoes and they dry in between.
