Our expert fitting advisor team has over 40 years’ combined experience as barefoot hoof care professionals, so we can help you understand how you can get Flex Boots to fit your horse in the best possible way. And if for any reason Flex Boots won’t work for your horse or pony, we will be honest about this - we never force-sell or make false promises.
Friendly expert advice
Everybody wants the best possible hoof boots for their horse or pony. The kind that are easy to use, comfortable for the horse, and protect the hooves. Our boot design does just that; Flex Boots work so well because they are designed to support a holistic, anatomically correct hoof care. After making sure that the horse's hooves are cared for correctly, the next most important step in hoof boot selection is getting the size and fit right.
Start by measuring your horse’s hooves and compare the measurements to the Flex Boot size chart below. Take the measurements ideally straight after the hooves have been trimmed, and at most a day or two after a fresh trim. Make sure to measure all four feet as they may differ in size.
Choose the right size boots
FLEX BOOT SIZE CHARTS
Flex Boots are available in two styles: standard boots that are 10mm longer than wide, and wide boots that are the same length as width. Please see the inside sole measurements of each style below.
Flex Boots fit hooves that are within +/- 5mm of the listed width measurements, and not longer than the listed length measurement. For advice regarding the best boot size for your horse, please contact us or your nearest retailer.
Note that if your horse's hooves are at the maximum width and length measurements for a specific size, the boot might not fit well and sizing up might be necessary.
For example, if your horse's hoof is 155mm wide and 160mm long (maximum measurements for size 150 boot), then the boot might not fit well. However, if the hoof is slightly narrower at 150mm wide and still 160mm long, the boot will fit well, as long as the heels are trimmed to the correct position. Flex Hoof Boots work better if they are slightly loose rather than if they are too tight, as loose boots' fit can be improved with Flex Pads.

HOW TO FIT AND ADJUST FLEX BOOTS
Our top tips for determining
BEST BOOT SIZE & FIT
Measure after a fresh trim
This is when the hooves are at the correct size and shape.
Hooves should be maintenance trimmed weekly, to retain the shape and balance of the hoof.
Measuring the hoof length
Imagine drawing a line across the back of the hoof, from heel to heel. From the middle of that line draw another line straight to the toe. This is where you measure the length of the hoof.
Take heels into consideration
When measuring the length of the hoof, do not measure the heel bulb, only the weight-bearing area of the hoof wall. It's also important to make sure that the heels are trimmed to the anatomically correct position before taking measurements.
Measuring the hoof width
Measure the width at the widest part across the hoof.
Take into consideration how the hoof grows between trims; you might need pads straight after a fresh trim, to get an ideal fit and to accommodate slight hoof growth between trims.
(Notice that this photo is taken after a weekly trim.)
How much the hoof grows between trims
If you do not trim weekly as recommended by us, you need to take your horse's hoof growth rate into consideration when selecting the most appropriate boot size. Our helpdesk can assist with this.
(Notice that this photo is taken before a weekly trim.)
What shape is the hoof
Flex Boots suit many different shape and size hooves. However, if the hoof width is over 10mm greater than the length, our boots are not ideal for your horse.
If you're not sure whether Flex Boots would suit your horse, email our helpdesk for free fitting and sizing advice.
Does the horse twist its legs
If the hoof is very narrow and the horse has a habit of twisting its legs a lot, it may be that our flexible boot is not suitable for your horse.
For some, a Flex Boot that is slightly looser works better than a tight boot. But primarily, the horse should be treated by a body worker, such as an equine osteopath, to correct the root cause of the twist.
We offer free fitting advice via email to help you determine the best boot size for your horse. For accurate guidance, please email us photos of your horse's hooves.
We need photos of clean hooves straight from the front and side with the camera on ground level, and a sole view, all taken on a clean surface. Ideally these photos should be taken within a day or two of a fresh trim.
