This is such a great boot.  I love them more every time I wear them.  Like all have said, they do run large.  I'm an 11.5 on the Brannock Device.  I shot for a 10.5 boot and they fit perfectly with room for an insole.  Which is good, because an insole with arch support is key with wearing these boots.  I wouldn't recommend standing in them without some.  I swear by the green SuperFeet insoles.<br />When not wearing boots, I pretty much only wear old school type sneakers.  Vans, Chuck Taylors, etc.  My sizes are as follows:<br />• Vans  Authentic lace up - 11.5(truest to the actual size of my foot)<br />• Vans Slip On - 11<br />• Adidas Stan Smith - 11<br />• Converse Chuck Taylor - 11<br /><br />Finally, if you decided to keep this boot, keep in mind that the leather sole is smooth, slick and very slippery until it is scuffed up a bit.  A decent walk on concrete will take care of that quickly.
