Hyperhidrosis of the feet, otherwise known as plantar hyperhidrosis is a common problem and can be treated with Iontophoresis. Botulinum Toxin treatment is not licensed in this country for hyperhidrosis of the feet and surgery is not generally recommended.
Cotton socks should be worn and feet left open as often as possible. Synthetic shoes and man made fibres tend to exacerbate this problem.
