I used a powder to remove foot odor before, and it was directly sprinkled in shoes or socks, and the effect was very good, but I forgot the name, only remembering that it was a brand from Taiwan Province Province. Dakening powder, white powder, can not only prevent feet from sweating, but also deodorize. You can sprinkle it in socks every morning, and you can use up to two bottles in a row. The shoes are dry and comfortable after use, and the price is not expensive. It used to be like 8 yuan, but now it's a little high. I don't know exactly, but the pharmacy may not sell it.
