Excessive sweating of the feet develops when your sweat mixes with the bacteria and fungus on your skin, shoes and socks. The combination of the micro-organisms, their excreted waste and sweat not only produces a bad smell but can lead to athlete’s foot, fungal toenails, itchy blisters and other fungal rashes.
Good foot hygiene is essential. If your feet sweat excessively, see a podiatrist. Treatment options are tailored to your symptoms.
