These heel socks do work, but you need to be consistent and patient. The socks are soft with a gel lining on the inside that basically traps your body heat and moisture—kind of like a mini spa for your feet. My heels felt noticeably softer after just one hour of wearing them. That said, I don’t love sleeping with socks on, so it took me two nights to get used to them. I even took them off the first night because I couldn’t stand the feeling. After five nights of use with nightly exfoliating, my heels are definitely softer, but still cracked in some areas. I’m hoping they keep improving with continued use. If you stick with it and exfoliate regularly, these socks definitely help soften rough skin. Not a miracle fix overnight, but a helpful tool for healing cracked heels.

A must for the summer

I was a bit skeptical about these after seeing on tik toc, but they really work. I have not had a pedicure in months and with these my feet remain smooth.

Enables the person to move around while wearing.

These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.
