NWT Dublin brand On Air Stretch Long Field equestrian riding boot. This boot is a leather boot with neoprene stretch material running vertically from knee to ankle. The boots are a 7.5 M with regular calf sizing in color black. There are lace and leather toe details along the front of the boot with zippers running along back of each boot. These boots have not been worn but have been in storage, so could use a quick cleanup (reflected in asking price). Thanks for looking!
