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!

Works for foot psoraisis
Size: 2 pairs black L
Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.
