A treat for your feet at the end of a work-weary day.  I bought them in blue just to try them out, and liked them so much that I will order the other colors.  They are soft and warm, but the knit is open enough that your feet don't get too hot.  I'd recommend these to anyone who likes soft, fuzzy slippers (and who doesn't?!).  Would love to see these in a mid-calf or knee sock.
