I was very disappointed with these moccasins as they were very loose/wide (even though I wear a medium and they say they are medium width).  When I walked around the house in them (had to put socks on so they'd stay on my feet) I could feel my feet sliding to the side.  Lengthwise they were perfect but even wearing socks, I knew I'd be in trouble if I walked around in these even a brief amount of time.
