Nice Socks, Bad Shipping
The socks are definitely worth the price. They are cozy and non constructive. They colors are nice. My only complaint is the method in which it was shipped. Slapping a mailing label on a clear bag is not acceptable. The shipper didn't consider protecting my privacy. I hate to think if it was something extremely private. Consumers deserve better when it comes to the content of their mail.

There’s room for improvement
These heel support socks are quite comfortable to wear, the cotton blend fabric is soft and breathable. The built-in gel continuously moisturizes the heels, and the effect is more noticeable than applying lotion alone. I usually soak my feet in warm water before bed, apply lotion, and then use these socks. The elasticity is just right, and they don't constrict my feet. If the gel coverage area were a bit larger, the protection would be more comprehensive. Overall, they offer good value for money and are a practical foot care item.

They worked
I got these for my elbows because I think I might have eczema on my elbow. They work very well. However I do wish they were a little looser. As far as putting them on your heels, the fit works well.

Good Results
I have always struggled with dry, cracked heels, but I’ve finally found a solution that keeps them consistently hydrated: these special socks with a moisturizing silicone lining on the heels. My heels now feel incredibly soft, but it’s important to note that consistency is key.
Wearing these socks every night before bed has made a significant difference. It’s not enough to just wear them once and expect results; you have to be diligent and make it a part of your nightly routine. After a few weeks of nightly use, my heels are much softer and no longer cracked.
What I love about these socks is how easy they are to use. Just slip them on before going to sleep, and the silicone lining does its magic overnight. By morning, my heels feel smooth and well-moisturized.
For anyone struggling with dry heels, I highly recommend these socks. Remember, the secret is consistency. Stick with it, and you’ll see the difference!

So comfortable!
These work great and very comfortable. I put these on with heel moisturizer cream at bed time. Heels were improved overnight. They are washable too!
