More in the news on "COVID Toes (also found on the soles)" as I had seen reported in my comment above. This report comes from the Chicago area, so it's not just the Spanish who are seeing it; it's been seen quite a bit in the USA, evidently, again, as the Spanish reported, in children and adolescents mostly. The CDC, however, has not yet designated "COVID Toes" as an official symptom.
