The feet have more than 250 000 sweat glands. Although the sweat usually does not smell, the bacteria, which in warm weather start reproducing faster, cause the unpleasant odour.
In most cases, sweating is due to physical activity, mental stress, or hot weather, and it is absent during the night. Some people though, experience perspiration as a result of minor activities or even without particular reason.
We advise to use foot spray against perspiration to reduce the risk of appearance of unpleasant smell or fungi.
