This pair of Doc Martens is in decent used condition. The tag that shows the size has been removed/worn out of the boot. I measured from heel to toe (outside of the boot) and it was 12 3/4". I measured the width at the widest point and it was 4 1/2". I'm a size 11 and it fits a bit loosely, so I believe it's an 11.5 or a 12 in US Size. Returns are accepted.
