There are many possible causes of foot rashes. Athlete's foot is one of the more common causes. Additional causes include irritant or contact dermatitis, allergic rashes from shoes or other creams, dyshidrotic eczema (skin allergy rash), psoriasis, keratodermia blennorrhagicum, yeast infections, and bacterial infections.
What Causes Athlete's Foot? Tinea pedis is caused by dermatophytes, which are fungi that infect the skin, hair, and nails. Sometimes yeast can cause foot infections and rashes, often between the toes. People who are prone to tinea pedis are also susceptible to toenail fungal infections (onychomycosis).
