Seem to help heal, but doesn't reach the balls of my feet
Size: 3 Pairs - Gray, Green, Pink
Only can wear when I am sitting down because they're to slippery to walk in

love these for soft feet!!
Size: 3 Pairs - Gray, Green, Pink
these are great. My feet are soft already! What I like best is my feet. Don't get hot in them because the heels and toes are exposed.

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.
