reddish spot cluster on feet

  A friend has noticed a rash like problem on his feet.  It started in one area looking like tiny red spots and began to spread.  It does not itch and are not bumpy.  It seems to be like miniature blood blisters.  
   He has tried using athletes feet medication with no success.

  Has anyone had any experience with this unknown problem?

Hello,
The first possibility that comes to my mind is of hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.
So please get this possibility evaluated. Till then, take some antihistaminic like Benadryl and apply some calamine lotion. If the symptoms persist then please get an evaluation done by a dermatologist. you may need topical and oral steroids.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
