Buy these!
Size: Regular, Color: Cream
I only write a review when I have a strong opinion and want to help others decide. I've been having trouble with cracked heels for months. Previously I had just been using regular socks, but these slip-ons have been game changers! They don't make my feet hot at night. They are comfortable and in the morning my heels feel soft, and I don't need to use them everyday. They look good and fit well even if I want to wear them under socks or in shoes during the day. They really do help if you have cracked heels along with some kind of lotion. Definitely effective!

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.
