I can't really put into words how great these slippers are.  I did have a hard time justifying myself to buy $60 pair of slips, but trust me, they are worth every penny if your feet are anything like mine. They are never, and I mean never, warm - not even with socks and/or shoes on. They are always ice cubes to the point where they are numb. My boyfriend is always warming them up for me (yeah, he's amazing), but I was hoping to change all that with these slippers and we both couldn't be happier. My feet are *actually* warm now! It's a miracle. They are great quality and get more comfortable with every wear. Use the chart to figure out your size (measure your foot to be sure) and you won't be disappointed.
