Re: Cracked skin under big toe
Fungus could be causing the cracking. Try using anti-fungal cream (Lamisil) and see if it corrects the problem. Also, when you wear shoes, change every day to allow time for shoes to dry out good. Always wear socks when wearing closed toe type shoes.
At night use a good cream for dry skin, under toes but not between toes and rest of feet, sleep in socks. You can mix a little Lamisil along with a cream for dry skin at night.
