See also my comments on the Crocs Men's Walu Relaxed Slip On,Khaki/Espresso,13 M Us.  I bought these 2 and the fit on this one is little more snug around mid-foot (top-side of my arch).  Maybe its the lining plus the wool socks I'm wearing or maybe the canvas material on the uppers that is not as forgiving/stretchable as I thought it would be.  I'm still satisfied with the purchase.  Great for walkabouts from house to the curbside, warm and comfortable for these winter months.
