Redness in the toes and soles of the feet often occur with athlete's foot or shoe dermatitis. WebMD also explains that redness also occurs with some bacterial infections, especially when the affected area feels painful to the touch. Dr. Gary W. Cole notes additional causes of foot rashes, including contact dermatitis, allergic rashes from shoes or other creams, dyshidrotic eczema, psoriasis and yeast infections.
Dr. Cole explains that athlete's foot often occurs at just the bottoms of the feet, but the space between the fourth and fifth toes also may have some moisture, peeling and dry flakes. He also states that sometimes athlete's foot may appear as small or large blisters of the feet, thick patches of dry and red skin or calluses with redness. MedlinePlus states that many people get athlete's foot from damp surfaces, such as showers, swimming pools and locker room floors, making it contagious.
WebMD describes shoe dermatitis, another cause of redness on the toes and bottoms of the feet, as an inflammation of the skin on the foot. This allergic reaction comes from contact with rubber, glue or elastic parts of shoes. WebMD states that symptoms of shoe dermatitis include burning and itching, mild redness and swollen, blistered and irritated skin.
