Maintaining good foot hygiene is the best way to prevent foot odour as it eliminates odour causing bacteria and removes dead skin cells as well as sebum. A foot file, pumice stone or chemical treatment, such as an Alpha hydroxy acid containing foot peel preparation, can be used to remove dead skin cells.[12][13] Using antibacterial soap to wash feet daily; keeping feet dry by changing socks daily and wearing cotton or wool instead of synthetic fibres can also help reduce moisture build-up.
