There are three reasons why your Scoot Boots may be forced open more than what is recommended: 1.     Your horse has not had a recent and correct barefoot trim. This could mean that the toes are excessively long, the hoof is too wide for the boot, or the horse is at the end of its 5-6 week trimming cycle2.     If the gap is more than 15mm (5/8”) wide after the break-in period, your Scoots may be a size too small. Please go to our Fitting Page to check the fit of your Scoots and contact our Sizing Team for help 3.     The walls of your horse’s hooves are too vertical and therefore not suitable for Scoots. Horses with contracted feet usually have vertical hoof walls, as do mules, which prevents them from getting a secure fit in Scoots Go to our Fitting Page or contact our Sizing Team for more information.
