For detailed instructions on how to measure your horse's hooves, see the video and instructions below. Below you will also find the sizing chart and tips for selecting the best size Scoot Boots for your horse. We are also happy to offer free sizing advice but we highly recommend considering our sizing kits so that you can be sure to select the correct size boots. Sizing kits are especially useful for horses that don't fit nicely into the ranges on the sizing chart. Note that the full sizing kit fee will be refunded if you decide to purchase a pair of Scoot Boots from us.  

Before measuring, ensure your horse has had a correct barefoot trim (i.e. rolled toe, beveled hoof wall and low heel). Measurements need to be taken within 2 weeks of a trim.

To get sizing advice from us: take 4 photos as as described below and send them to

  • 1st photo - start your tape measure at the center of the toe and work backwards over the frog towards the heels, keeping the tape against the hoof. Do not start at the heels and work forwards 
  • 2nd photo - place your tape measure across the widest part of the hoof
  • 3rd photo - front of hoof which shows shape
  • 4th photo - side of hoof to see height of heel bulbs 

 If your horse clearly has two different sized hooves then you will need to send us sizing pics of both hooves.



To measure your horse yourself after a fresh trim: 

Step 1

With a ruler or tape measure, measure the LENGTH from the GREEN line at the tip of the toe to the GREEN line at the rear of the hoof at the very end of the heel buttresses (to ensure you have located this position run a rasp across both heels and the correct measuring point is the last part of the heels that physically makes contact with the rasp before the heels drop away towards the collateral grooves) DO NOT MEASURE FROM RED LINE INDICATED BELOW.

Step 2

Measure the WIDTH of the hoof at the widest part and select the correct WIDTH.

Step 3

Now that you have the LENGTH and the WIDTH go to the size chart below and select your size, and see our notes below if you're unsure of what size you need.


Notes about Sizing:

  • Measure after (within 2 weeks) of a correct barefoot trim so that your horse has a rolled toe, beveled hoof wall, and low heel.
  • Sizes increase in 5mm (3/16”) increments.
  • The sizing chart is designed to be referenced after a fresh trim but it is calibrated to account for growth between trims.
  • If you require two pairs of Scoot Boots (for example front and back) but are unsure of the sizes you need, we recommend starting with one pair and using it as a reference point to determine the other sizes you need. You can use our sizing shell fitting video to evaluate fit:  

What if my horse's measurements don't fit nicely in one of the size ranges?

  • If your horse doesn't fit nicely within one of the sizing ranges, we highly recommend using a sizing kit - we find Scoot Boots work well on many hoof shapes, but often you'll need to try a few sizing shells to see exactly which size will work best.
  • General rounding rule: select the smaller boot size if you are between the size measurements. For example if your hoof length measurement is between 121mm (4 13/16”) and 124mm (4 15/16") long, select the hoof measurement of 120mm  (4 3/4”) on the chart meaning you would need size 3.
  • For hooves that are different sizes: If your horse's two hooves have slightly different measurements (i.e. one hoof is in between sizes), select the boot size that matches the largest hoof. However, if one hoof is a full size smaller, you can purchase Scoot Boots in singles to do a mix-matched set (just let us know if you don't see the size you need in-stock for the singles and we'll move some for over you). 
  • For WIDE hooves: If your horse’s hooves are 10mm (3/8") wider than long you need to select the size from the ‘maximum’ width measurement and not length measurement (for example, if your hoof length is 110mm (4/18") and width is 120mm (4 3/4"), you select size 2). However, if your horse's hooves are wider than long you may have excess flare that should be addressed by appropriate barefoot trimming practices. Excess flare may cause the sizing to be off as the measurements of the bottom of the hoof will not reflect the overall volume of the hoof, so we recommend using a sizing kit to determine the best size. If the hoof width exceeds the hoof length by more than 10mm (3/8"), then Scoot Boots may not be suitable for your horse. We've had good success fitting Scoot Boots to these extra wide hooves, but the sizing shells are necessary to determine which size will work best.
  • For NARROW hooves: If the hoof length exceeds the hoof width by more than 10mm (3/8") then Scoot Boots may not be suitable for your horse and you would need to using sizing shells to determine if they will work for your horse.
