Comfortable & Ideal
Color: 2 Pairs: Black
As a hot sleeper, I could never wear regular socks to bed, so I thought I’d try these. They have been comfortable and ideal for my needs. They’re easy to slip on and I take them off before I get out of bed. They’ve been great and my heels look WAY better after just 3 nights. Happy with the purchase!

Great buy for rough heels
Color: Gray
These work great on hubby's feet which are always so dry. Just have to be consistent. They fit great and are comfortable he says.
