What is Plantar Hyperhidrosis?

Plantar hyperhidrosis is a disorder characterized by excessively sweaty feet. It often accompanies Palmar Hyperhidrosis, severely sweaty hands.

Cause of Plantar Hyperhidrosis

Plantar Hyperhidrosis is caused by hyperactive sweat glands in the feet in response to stressful situations, increased temperatures, and other instances. Everyday activities may excessively stimulate the sweat glands in the feet leading to unusually sweaty feet.


Symptoms of Plantar Hyperhidrosis

  • Excessively sweaty feet
  • Slipping easily out of flip-flops and sandals because of extremely sweaty feet
  • Shoes are easily ruined because of salt minerals from sweat

How is it diagnosed?

Your doctor may recommend a series of tests to pinpoint the feet as a location of excessive sweating and determine the severity of the disorder.

Plantar Hyperhidrosis Treatment Options

There are a variety of therapies available to treat plantar hyperhidrosis including antiperspirants, iontophoresis, Botox®, and combination therapy.

  • Antiperspirants – Used to prevents sweat from reaching the surface in hands, feet, and underarms.
  • Iontophoresis – The best treatment for sweaty feet. It utilizes a mild electric current through water to reduce hyperactive sweat glands.
  • Botox® – Temporarily binds receptors to prevent activation of sweat glands. This can be very painful and treatment usually wears off in 3-4 months.
  • Combination Therapy – Over-the-counter products such as shoe inserts and foot powders combined with antiperspirants or iontophoresis to reduce foot sweating.
    • Shoe inserts help absorb sweat and prevent shoes from being ruined by sweat. SummerSoles® shoe inserts can even be worn with flip flops or open toe shoes.
    • Foot powders can help absorb sweat: Gold Bond® or Scholls’s® are designed especially for sweaty feet.
