Why do some ppl have a thick growth of skin on the bottom of thier feet?

Answer:
It's calluses --- just like people who work with their hands develop calluses on certain spots on their hands. Calluses protect the inner layers of skin. Your feet have to endure a lot to every day to get you where you need to go... be kind to them! PS -- You can buy assorted scrubs, lotions, creams, or even a razorblade device to get the callused skin off of your feet. There is a whole industry surrounding it.
