I almost always use Old Friend slippers but decided to try these as I love the red color...I'm impressed...They are stong like shoes but comfy right out of the box...Thick soles are strong enough to use as shoes...Fleece is nice and thick. Love the red color and other colors as well and They are half the price of my favorite Old Friend slippers...Curious to see if they'll last as long...If you want to wear socks or if you are a half size, probably size up.. Also they run a bit narrow for my wide foot like all womens shoes do..... Happy with this product so far and very happy with the price!
