The B-52 by Bullboxer Men's Slip-On Lined Clog Shoes are an insulated option for casual occasions during the fall, winter, and spring seasons. The shoes feature a solid gray PU upper material with a round toe shape and slip-on closure. The faux fur lining material and leather outsole provide added comfort and durability. The shoes are available in US size 13 and EU size 43.  These 13's ran smaller than other 13's I have purchased and were a little too snug for me to wear comfortably.  They have sat in my closet for about a year and have never been worn.
