I love these slippers!  I searched for ages trying to find a slipper that had decent support and these fit the bill perfectly. I have a narrow foot with a high arch and these fit me well.  They do stretch as you wear them but can be tossed in the wash and they return to original form.  I am not sure these would be the best option if you have very wide feet but for me I could not be happier!  I was hesitant on spending this much money on slippers but now I plan on purchasing the same style with an outdoor sole.  However, I have gone to the mailbox, the porch, or the car in these and they have done just fine.  Also, the soles provide great traction on hard wood.
