New stunning Born black suede tall boots in size 10 wide calf. Laying flat, the side to side measurement of the boot at the top when zipped and tied tight is approx. 8-3/8". There is a suede insert at the back of the calf where the laces are that allows for making the calf wider, if necessary. It measures approx. 3" across at the top and decreases in width the further down it goes. Long black laces allow for great adjustment for the width (see photos). Inside full zip. Heels are a little over 1-1/2". New, never worn.
