Superb boot, with a design based on many of the Mountain Horse accredited function systems such as the Stirrup Control System. The elasticated inset in the calf gives a perfect fit, whatever your size. The zipper all the way down the back of the boot makes it easier to pull on. Strong leather, which is soft and supple, provides excellent contact with the horse. Scotchguard ® treated leather will repel water and dirt. Calf measurements (A) and height measurements (B) are in inches.
