Jeffrey Campbell Rainboots. It was listed S a size 10 and I saw no marking on the boot for size. I guess it’s stamped “40” which I still cannot find. They measure under 10.25 inches which is far and away no “10”. I wear a 9.5-10 and couldn’t even begin to get these on. So I will list accordingly unlike the previous lister (not this site!) who didn’t bother to let the buyer know they ran extremely small-more like an 8-8.5 in woman’s.
