These are definitely among the most beautiful equestrian riding boots I have come across to date!  They are a European size 39 which converts to a woman's U.S. size 7.5 B or men's size 6 D.  The calf skin boots were hand made in Spain by El Estribo.  If you go to the El Estribo site, you will find these are El Estribo model 1231-SE in Ternera Flor Marron.  The boots retail for $325.00 Us Dollars.  The boots zip conveniently up at the front.  There is a leather strap that buckles at the ankle and another at the top of the boot.  These boots are made with durable Goodyear rubber soles.  The inner sole has some padding so these should prove to be quite comfortable. They are 17 1/2" tall at the highest point.  To be on the safe side, I am calling the calf a narrow calf.  I think that is the case, especially if you will be tucking riding breeches into these gorgeous English equestrian riding boots. The boots are in excellent condition but for the tiniest bit of wear at the back strip above the heel on one boot.  I provided a photograph of this.  They were stored in a tack trunk, for a bit of time, so have a very slight odor from storage.  Certainly that will fade, and I don't think it is objectionable as it is.  These are gorgeous well made boots!
