This is my third pair in ten years. I bought past pairs at CVS, but they only sell it seasonally. One shoe got caught under a door (thankfully without my foot in it) and ripped the last pair. Amazon to the rescue. Cheaper here though. The last time I bought a pair, they were $20 a pair at Amazon. These are comfortable and surprisingly supportive. The contour is similar to the contours of my orthopedic inserts. I use them as slippers around the house.
