My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me.
After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress.
A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer.
The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore.
They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new.
If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

Is this the CURE!
Size: Regular, Color: Cream
I have a skin disease called Ichthyosis Vulgaris. Yes, SCALEY FISH! Thanks MOM! This unfortunate crud leaves my heels an embarrassing mess! They are cracked and dry and literally like concrete. I have had this disease all my life and there is NO cure. It's hideous! Anyway, I have tried so many different experiments to help improve my situation. So much time and money I will never get back. So when I saw these, I had to give them a try too because I am a forever optimist and love being disappointed. Here's how it went.
First I put my dermatologist recommended AmLactin on my crusty heels. Then, I put the socks on. By the way, with no problem at all, and went to bed. I was not too hot, which is usually what happens when I sleep with socks on. I never even realized that I had them on. When I woke up, I took them off and immediately used a "Heel File" over a towel removing all the yuck!. Then, I sand papered them to smooth the skin out. Then, I doused them with Shea and Aloe foot lotion I found at the bottom of my experiment drawer in my bathroom. Oh, they felt like someone else's feet. I am very hopeful at this moment! Is this the cure to my embarrassing situation? I sure hope so. Spring is here and I would really like to wear my cute flip-flops when I go to the Waffle House and set at the bar. Wasn't that a picture on Facebook of someone nasty heels? It made me gag. Then, I had to make sure that picture wasn't me! I am going to do this for a week and come back for another review. Wish me luck ya'll!
UPDATE!
So it’s been about two weeks. I wish that I had taken a before and after picture. I guess I figure that this too will be a waste of money. NO! These little socks are a God send for me. I did buy AmLactin foot repair cream and that I highly recommend. It’s the best so far. They also offer an option with heel socks. They are soft and work very well also but one negative. They leave fuzzies on you feet and tools. Guys this is it for me. My search is over! I went to my mani/pedi queen yesterday and she was shocked when she saw my feet. She is spreading the word!
