Vintage 9Os Nine West lace back riding boots

What a find! These boots are 15 inches tall and 6 inches wide at the top. The heel is 3/4 of an inch. The leather on the outside is an excellent condition, but the leather on the inside is flaking. There is no size marking, but compared to other boots they are most likely a size 8, possibly an 8 1/2. The length of the sole is 10 1/4 inches and the width is 3 1/4 inches at the widest point.
