The first time I put these on it was hard not to notice there was a hole in the toe. The toe seam hadn't been properly sewn. I didn't want to send them back because I was desperate for something to keep my feet warm and these looked so snugly and cooshy and they were fuzzy inside, I wanted to keep them. I patched up the hole and slipped my feet into them. Ooo! They felt so good! I thought, I never want to take these off, I will live in them and have stinky feet forever. After a while, yet still that same day, I gradually began to notice, hey, my feet are getting cold. They're not supposed to do that. I have heat holders on and my feet should be toasty warm. Where's the heat. They aren't holding the heat. I began to fall out of love with them. Now I feel betrayed and lied to.
