What should you know about heat spots on feet?

Warm, sweaty shoes and sock friction can irritate skin and block follicles. Tiny itchy bumps may be heat-related, while tender bumps around hairs can fit folliculitis. Spots between toes may have a different cause from bumps on the top of the foot. Cracking, scaling, blisters, or drainage are useful details for diagnosis.

Wash gently and dry carefully, especially between the toes. Change damp socks, rotate shoes, and choose footwear that allows airflow. Avoid scratching, popping, harsh antiseptics, and thick fragranced creams over active spots. Do not share towels or footwear if drainage is present. A clinician can recommend treatment after examining the location and skin surface.

Book an assessment if the spots keep returning, interfere with walking, crack, ooze, or fail to improve with drying and reduced friction. Seek prompt help for rapidly spreading redness, severe swelling, fever, red streaking, or a wound that is slow to heal, particularly if you have diabetes or reduced sensation.

Ask whether the spots are caused by sweat, friction, follicles, or another condition; whether footwear or a product is contributing; and what to use safely on the feet. Describe itch, burning, pain, scaling, blisters, drainage, and when the flare began.
