I’m totally unsure if this just dry skin or if it’s a fungal infection/athletes foot or something else?

My only symptom is dry flaky skin peeling off the bottom of my feet. No pain, no itching, no other symptoms? Google tells me it could be either and sometimes athletes foot only symptom is dry peeling skin.

Part of my thinks it’s just dry skin bc: the weather here recently changed and is cold and dry now. I also really enjoy taking long hot shows and baths. Which all cause dry skin. But this has never happened to me before so suddenly and quickly.

I also just returned from a 2 week hiking trip abroad where I was on my feet hiking in very high altitudes in very cold weather over 75 miles and alot of elevation. I used hikegoo on my feet to prevent blisters during this time…. Maybe it’s related to that?

On the other hand, I did use a communal shower barefoot in one of the huts on the trail…. Which points to a fungal infection/athletes foot?

Input/advice appreciated!
