Causes of Foot Rash

12/12/2018 by Oath Creative

There are a few conditions that make up the majority of foot rashes. Some are infective (caused by dermatophytes or bacteria), some are non-infective, and some come about due to an overly active immune response from the body.

Below are the 4 most common conditions that present as a foot rash.

Tinea Pedis

Cause: Dermatophyte infection of the foot

Appearance: Moist skin between the toes, painful fissures and peeling skin

Treatment: Topical anti-fungal cream (with topical corticosteroid if skin is inflamed), good foot hygiene, leave shoes in sun, keep feet dry

Contact Dermatitis

Cause: Direct skin contact with allergen (nickel, nail cosmetics, detergent)

Appearance: Localised redness, itchiness, swelling where skin contacted allergen

Treatment: Avoid contact with allergen, moisturiser, topical corticosteroid cream

Atopic Dermatitis (Eczema)

Cause: May be influenced by genetic factors

Appearance: Localised redness, itchiness, swelling commonly in skin folds (behind knees, front of ankles)

Treatment: Moisturiser, topical corticosteroid cream


Cause: There can be multiple causes, but it is aggravated by stress, alcohol, and obesity. It is classified as an Immune mediated inflammatory disease.

Rashes can be very hard to identify. If you have a rash on your leg or foot, we highly recommend you get it assessed by a Podiatrist or General Practitioner. If you are experiencing redness, swelling, pain, heat, and throbbing in your foot, it may be an indication of a severe bacterial condition in your foot. These infection can get out of hand very quickly, it is therefore important to get the area assessed by a General Practitioner as soon as possible.
