Fungal infection - it needs to be treated by professional. Treatment varies between 6 months to 2 years, sometimes longer for some. Treatment is basically regular debridement to expose fungus and weaken activity. Plus, eliminating the source: shoes, boots etc. Fungus likes dark and moist environment. Your shoes/boots have the best place for them.
Hot water and sun light are very effective against fungus.
