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

Transformative for Dry, Cracked Heels!
Color: Original Grey
I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough.
Effective Moisturization: These socks are infused with moisturizing agents that work wonders. After just a few uses, I noticed a significant reduction in dryness and cracking on my heels. My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin.
Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed.
User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine.
Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time.
Final Thoughts: If you're struggling with dry, cracked heels, I highly recommend Dr. Frederick's Original Moisturizing Heel Socks. They are a fantastic investment in foot care and have made a noticeable difference in the health of my skin. These socks have become a must-have in my self-care routine!

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.
