Cracked heels are gone after 5 applications
Size: Regular, Color: Cream
These moisturizing socks work great. My heels are happy again. The open toe design makes it so my feet don’t overheat at night. It only took 5 times to get rid of my painful cracked heels. Now I wear them 1-2 times a week to keep my heels healthy.

Really nice but needs a few small improvements
Size: Regular, Color: Cream
Super comfortable and the gel lining feels so nice on my feet. They seem to do their job and help with moisturizing and so far the quality has been great. I deducted a star because they can be difficult to clean and may not fit wider feet. Otherwise a great value for your money

Perfect socks for cracked heels
Size: Regular, Color: Cream
These are the best for your cracked heels. They still keep their shape and softening power even after washing.

So So Socks
Size: Regular, Color: Cream
These are very comfortable socks. I machine washed them on a gentle cool water cycle and they ravelled. That is disappointing quality.
