Loose socks, no distinction between brands. Personally, like the landlord, I like to wear socks that are a little tight, and I don't like the feeling of loose feet. Such socks have nothing to do with the brand. According to my experience, such socks have two conditions: first, the cotton content is relatively high, at least above 80%, the higher the better; The second is thickening, even if it is thin. Mainly because cotton has shrunk to some extent after washing, and its elasticity is slightly poor, so it is not easy to loosen. If it is other elastic materials such as nylon, once the elasticity fails or ages, it will come loose. To tell the truth, such socks are really hard to find. At present, I bought an atomic bomb with the highest cotton content and thickening. The above experience is for the reference of the landlord.
