I wear a size 14 shoe and I ordered the XL Gotham 100 boots. These fit perfectly and seem to be made of a decent quality material for the price paid. I have pretty large legs so I was worried about fitment in the calf, but these actually have plenty of spare room in the calf which may be a bad thing if you want really form fitting boots ( I'm 6'3/6'4 and close to 250 lbs+ to give you an idea of my measurables). These will look great with my Batman costume
