I bought these because I got them on a great deal and was quite skeptical, but they actually worked exactly as advertised and I saw a huge difference after the first night! I understand why they don’t cover the whole foot like a regular sock (it would be stifling), but it would be incredible if they made a pair that go forward enough to cover the ball of the foot. One pair lasted about 3 weeks before the moisturizer wore out (I did notice a dropoff after washing, so for best results put them on when you’re clean and just for overnight, so you can avoid washing). Apologies for no photos- no one wants to see the before photos. These work so well I’ve just come back to order more even though I’m now paying full price. Definitely, definitely recommend.

A game changer for deep heel cracks and psoriasis!

Color: Original Grey, Color: Original Grey

If you have deep cracks or psoriasis on your heels, get these they are a total game changer! They hold in Vaseline and topical meds perfectly while I sleep, providing much needed relief without getting all over my sheets. My heels are healing faster and my callouses are softer and don’t split open because the moisture is trapped against the skin all night with the built in gel cushion lining instead of rubbing off. So much hydration. The fact that it is a 2 pack is perfect because while one pair is being washed and drying, you still have a set to wear. Very soft, stretchy, breathable, and easy to sleep in. I highly recommend them!
