My New Toeless Socks
These toeless cotton socks have been my go to socks, I have had twelve surgeries on my foot due to a car accident on my right foot. I cannot wear close toe socks as the cause swelling and pain, now I can wear these soft toeless socks with no pain or swelling. I love I have the option of three different colors as well.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
