This is the third pair of Acorn slippers that I have purchased.  I like the variety of styles and patterns, especially the faux fur options.  I purchased these in Chinchilla and the color is a cross between a dark gray and a dark brown.  There is a nice tread on the bottom, making them non-slip and appropriate for quick walk to the mailbox.  I live in Wisconsin and we are currently enjoying some sub-zero weather.  The slipper is toasty warm and comfortable.  I tend to wear heavy thick socks.  I ordered my normal size slipper and these work fine with both regular socks and my thick ones.  The slipper is easy to take on and off.  Acorn is a quality product and worth the price.  I am very pleased with this purchase.
