Tips for your Cavallo hoof boots to ensure the best fit and HOOF TRIMMER SUPPLY Satisfaction guarantee! 

New UNUSED, UNALTERED clean boots will be 100% exchanged to insure the perfect fit. To keep the boot clean in the fitting process, we suggest covering the hoof with thin plastic (a trash bag or shopping bag works well) and checking fit on a non-scuff clean, dry surface. To be safe place a piece of cardboard under the boot to prevent scuffing.

Cavallo (all models)

The process is very simple

1 ) Measure the hoof  carefully just AFTER A FRESH TRIM.

2) Measure the length from the heel buttress line to the toe.  Do NOT include heel bulbs. (Refer to the diagram)

3) Measure right across the widest part of each hoof.

4) Compare your measurements to Cavallo sizing chart below.  Stay within the boot size range as room for growth has already been allowed for between regular trims.  The Cavallo Regular sole is best for a hoof that is measuring the same length and width. The Slim sole is 1/4 inch (6 mm) narrower than long and better suited to a more oval shaped hoof.

5) Please re-measure if the length is greater than the width by two sizes, 1/2 inch (12mm) or more. 

Simple Fitting Tips:

  • SOLE: The sole of the hoof should fit securely inside the boot sole. Ensure that the entire weight-bearing wall from front of toe to heel buttress sits within the Simple Boot outsole. It may be helpful to compare the outside raised tread area at the bottom of the boot to the weight-bearing length of the hoof sole (toe to buttress as per diagram above).
  • OUTER COVER: Ensure that the boot tongue is pushed firmly against the hoof. Draw the outer flaps firmly around the hoof, pressing the Velcro on the flaps against the Velcro on the tongue; keep taut and level.
  • TWISTING: If the boot twists or moves excessively, it may be too big or the outer cover may be loosely fastened.
  • TOO SMALL: If you have difficulty putting the boot on, it may be too small. Ideally the boot “snaps” nicely onto the hoof for a good fit. Please check your measurements against the chart above.
  • PASTERN WRAPS may be used to assist in the breaking-in process to prevent chafing.
  • *ONCE THE BOOT IS FITTED, if the strap extends beyond the nylon keeper, then you can cut the strap to the preferred length, leaving a line of stitching to prevent unraveling. (Only applies to Simple Boot)
  • *PLEASE NOTE: Boots cannot be exchanged if straps have been cut. Be sure boots are correct size BEFORE cutting.

Before Your First Ride

(Only new clean UNUSED, UNALTERED boots can be exchanged.) 

Like your own riding boots, it is recommended that time is taken to gradually break in your Hoof Boots. If your horse has sensitive skin, or if you are going on a long ride and are concerned about potential rubbing, Cavallo Pastern Wraps are available. If your horse is fine boned and there is excess space between the pastern and the boot collar, wraps can also prevent major debris from entering the boot.

EASY BOOT Fitting Tips:

  1. Measure the width of the hoof across the bottom at the widest point. This should be done after a fresh trim.
  2. Measure the length of the hoof from the toe to the buttress line of the heel. The buttress line is the farthest weight bearing point of the heel where the hoof wall ends. Do not include the heel bulbs in the measurement.
  3. Compare your measurement with the appropriate size chart. Please note that each boot style has its own unique size chart.
  4. Ideally, the length and width measurement will fit into the same size. If the length and width measurements indicate different sizes, select the larger size. If the width and length measurements are different by more than one size, your selected boot style is not recommended.
