Having sweaty feet is completely normal. After all feet are very hard working! On average feet can produce a shot glass of sweat a day, and sometimes more. Causes for this can range from heat, exercise, if taking medication or simply is heredity. Certain socks and shoes can have an impact too. Plastic footwear, which is becoming more and more common now and can hardly be differentiated from leather, are hotbeds for creating sweaty feet. You may as well be wearing plastic bags. Shoes with nylon lining, shoes which close tightly (safety shoes) and rubber boots stop the feet from breathing and moisture can’t evaporate.
In these types of footwear, the sweat will gather and starts to form skin flakes, and will become an ideal breeding ground for bacteria, especially if it is hot inside the shoe/boot. This bacteria will rapidly multiply and start to cause sweaty smelling feet, which normally would be odourless.
