Mone have mass crevasses in them and if I wear thongs for to long they can bleed - thats how deep the cracks are!! ...
This is what I have, from wearing no socks mostly.
At any one time i can heave 2-3 cracks on each forr that are very painful to walk on and can bleed

Wearing socks and closed shooes does help a lot, and ego heel balm is great but it stings when they are open cracks?

Im going to google milky feet that sounds awesome.
