If the patient has symptoms of sweaty, smelly feet, then there is a greater likelihood of having a condition such as odorous sweating or restrictive hyperhidrosis. However, it is important to note that lifestyle and environmental factors such as wearing thick footwear and working in a hot environment for long periods of time can also lead to sweaty feet, and diseases such as tinea pedis can also lead to smelly feet. If there is no improvement after adjusting lifestyle and environmental factors, then a medical problem needs to be suspected.
