The foot fungus tinea pedis is anaerobic, which means that it can only survive in an environment without free oxygen. It dies in an oxygen rich environment.
Since the outer layer of the skin is exposed to air, tinea pedis hides in the skin and chews away at the moist tissue. When the tinea pedis chews deeper and deeper, it bites into the flesh and leaves a big gaping wound. Living raw flesh after being bitten into and exposed, bleeds.
The tinea pedis will fester, continuously chewing into the raw flesh to hide from oxygen. Tight socks and enclosed shoes provide an ideal moist and warm environment for the tinea pedis to grow and multiply, and the bleeding open wound continues to bleed, and bleed, and bleed.
Wear sandals. Expose the toes and the feet to the open air. Wash the foot with hydrogen peroxide on a daily basis.
