Choose 3 shells to try on your horse, it is usually best to choose the closest size as your middle boot size (for each individual hoof) e.g. if your horse looked like needing a size 3, you would chooce the 2.5, 3 & 3.5 mini kit to try. If the hooves are different sizes, the other hoof for example measuring up at a 2.5, you would be best to also hire a 2, 2.5 & 3 mini fitkit to try on this hoof. The easycare fit kit has been designed to help you find the correct size glove or glue on for your horses hooves. These brand new revolutionary hoof boots from Easycare are lightweight & simple, & fit the hoof seamlessly. As the glove & glue-on easyboots do not need any hardware or fastening systems, achieving a good fit is more important than ever. As proper fit is so vital, Easycare decided it would be best to offer these boots in half sizes to ensure a perfect fit for each individual hoof. Each shell has only four millimeters of width difference between the next shell size up or down. This tight gap between sizes helps ensure a snug fit, but it also means that there is little room for error in measuring & determining the proper size of boot. The Easycare Fit Kit allows consumers to fit their horse''s feet in the Glue-On and/or Glove shell before ordering, to ensure the best fit possible without the hassle & wasted time of buying & returning multiple boots. Pre-fitting in the shell will ensure a perfect fit in both the Easyboot Glove or Easyboot Glue-On hoof boot lines & is especially helpful if your horse is between sizes or has one foot a slightly different size to the other. The shell used in both the Easyboot Glove & Easyboot Glue-On products is flexible & has a great deal of stretch. Although taking hoof measurements is a great starting point for fitting any hoof boot, the Fit Kit will allow you to see for certain if a the easyboot glove or glue-on will fit your horse''s feet well, & exactly which size fits best.
