Is there any dead skin that appears as a mesh/web? Check the balls of your feet and if you have several holes on the surface of the skin that appear in clusters, you have pitted keratolysis. Now, this in itself often does not required treatment, however, since you've reported itchiness this could make it progressively worse. Athletes foot is treated easily by over the counter medication (I highly recommend the spray but don't put socks on straight after). If your feet have a potent smell around the affected area, have brittle or yellow toe nails or any, pain or severe inflammation, let us know please. For now, dry your feet well after a shower, don't wear tight or damp footwear and please do not put your fingers in your mouth after contact with your feet.
