Frequently, the center point of the injury has normal-appearing skin with a ring-shaped edge, leading to the descriptive but inaccurate name ringworm. (It is inaccurate because there is no worm involved.)
Between the toes (the interdigital spaces),athlete's foot may appear as inflamed, layered, and soggy tissue. Parting of the skin (gaps) might be available between or under the toes. This type of athlete's foot tends to be very itchy.
On the sole of the foot (the plantar surface),athlete's foot may appear as pink-to-red skin with scales running from mild to widespread (diffuse).
