    The answer to calloused feet.
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.

    Slippery when wet!!!
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    “These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”

    Love them
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

    Effective but may be uncomfortable
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.
