@dr.heatherderm: Foot fungus and warts can be spread through moist floors. You can walk around public spaces like swimming pool decks and locker rooms with flip flops to avoid this. Foot fungus that infects the toenails is hard to treat, as are foot warts, and its much easier to prevent them in the first place. #dermatologist #dermtok #skintok #dermatologytips #footfungus #athletesfoot #footwarts #dermatologistexplains #dermdocheather
