Medial/Lateral Extensions

Medial/Lateral ExtensionsTwo options to aid in the treatment of conformation issues in foals and yearlings. Both the urethane and aluminum extensions offer correction with a balanced hoof capsule that is more symmetrically loaded.

Common Issues with Traditional Methods

  • Corrective trimming on young horses lowers either side of the foot
  • Uneven loading on the hoof capsule creates distortion and flares

Medial/Lateral Extension Solutions

  • Treats angular ankle deformities and supports unstable knees with a balanced hoof
  • Used mostly in “toe-in” situations
  • BOTH the Urethane and Aluminum extensions can be flipped or use on any foot medially or laterally!

An ALUMINUM Extension

These direct glue shoes have been used extensively since 1999 in the central Kentucky area on Thoroughbred foals and yearlings.


  • Easily shaped to fit the abnormal foal or yearling foot
  • Very thin profile allows normal frog and sole loading
  • Limits movement when healing or helping prevent coffin bone wing fractures
  • Strong bonding to all acrylic adhesives
  • Minimal surface prep
  • Easily drilled for application of traction devices

A URETHANE Extension

Thin, flexible urethane encourages natural growth patterns and helps “correct” angular limb deformities in foals and yearlings.

The narrow side heel of the urethane extension has been left full to cover a wide range of foot shapes. If necessary it can be easily removed with a grinder before application or with a rasp after application.

Polymer Forge™The THINNEST urethane shoes on the market:

  • Allows application to only one foot without excessive lengthening of the limb
  • Enhances normal frog pressure with or without injecting pad material because foot is closer to the ground


  • Promotes a natural growth pattern during corrective treatment
  • Hoof experiences expansion and contraction in a natural fashion
  • Flexibility makes removal easy when starting at the narrow heel
  • Superior bonding to all acrylic adhesives
  • Minimal prep work
  • Deliver superior wear resistance
  • 25-30% lighter than metal extensions
