The ideal tool for determining proper sizing for the Easyboot Glove, Glue-On and Glove Back Country. The Fit Kit allows you to fit your horse's hooves before purchasing boots. Get the best fit possible without the inconvenience of buying and returning boots. The EasyCare Fit Kit lets you try three different sized boot shells - one in the size you specify, one a half size larger, and one a half size smaller. For example, if you order a size 2 Fit Kit, you will receive sizes 1.5, 2, and 2.5. Please Note: At this time the Fit Kit is only available to customers in the United States.
