Duplo Horseshoe Sizing & Shape Guide
Correct fit is essential for functional hoof protection. A well-fitted shoe supports balance, movement, and long-term hoof health.
Duplo horseshoes are sold individually, so you can mix sizes and shapes as needed for front and hind hooves.
Step 1: Choose the Right Shape
Start by looking at the trimmed hoof from the bottom and evaluate the overall outline.
-
Round outline → commonly seen on front hooves
-
More oval outline → often seen on hind hooves
Round models, STS (Straight Toe Shoes), and open-toe versions are frequently chosen for front feet. Oval shapes are often selected for hind feet. Individual horses vary, so hoof form and movement matter more than general rules.
What Is an STS (Straight Toe Shoe)?
STS models have a slightly straighter toe area. This can allow the shoe to be positioned slightly farther back under the hoof, which may support smoother breakover depending on trim strategy and gait mechanics.
If you choose an STS model with quarter clips, the clips are positioned slightly farther back compared to standard round models.
Step 2: Select the Correct Size
Duplo composite and pure urethane horseshoes are sized at their widest width.
- Smallest size: 50 mm
- Largest size: 198 mm
- Size increments: 4 mm
- From 182 mm upward: 8 mm increments
You’ll see sizes like 110 mm and 114 mm (not 112 mm). If your horse measures between sizes, a slightly larger shoe can be carefully adjusted with an angle grinder.
How to Measure Correctly
For accurate sizing, measure a hoof that is ready to be shod:
- The hoof must be bare and freshly trimmed.
- Do not measure over an existing shoe.
- Avoid measuring an overgrown hoof.
Measure the width and length of the hoof at its widest points. The width is typically found slightly behind the apex of the frog.
Measuring hoof width at widest part.
