Old Mac's G2 Multi-Purpose Horse Boots Sizing

Before you begin taking hoof measurements, please ensure your horse has a fresh and accurate trim.

Simply follow the steps below to select the correct size. Feel free to contact our friendly staff for assistance. Sizing is imperative to a good fit. We cannot exchange used boots.

Old Mac’s G2 are available in 11 sizes (0-10) with each size increasing by 5mm (3/16 inch) in width and length. It is important to note Old Mac’s G2 sizes are in no way comparable to metal shoes sizes.

The unique design feature of Old Mac’s G2 allows for width and length adjustment and is therefore generally suitable for both wide and narrow hooves. Old Mac’s G2 sizing allows for natural hoof growth between trimming. If your horse’s hooves are excessively long and narrow, Old Mac’s Inserts are available separately.

Immediately after a proper trim measure your horse’s hooves. If you intend to use Old Mac’s G2's over metal shoes for transportation then you must take your measurements AFTER shoeing. Correct size selection and proper fitting is very important and will ensure maximum performance from Old Mac’s G2 Multi-purpose Horse Boots™.

How to get the correct size boot for your horse:

1. Trim Hoof - Before measuring, ensure your horse’s hooves have been correctly trimmed with all flare and excessive length removed. We also recommend that the edge of the hoof wall, where it meets the ground, be beveled (rolled) with a rasp. This removes the sharp edge of the hoof wall and prevents chipping and white line separation.

2. Select Size - Accurately measure the length and width of your horse’s hoof at the widest point. From the charts below, select the size that matches the measurement.
