Why is this boot lined with ThinLine?

  • Our trademark open cell technology delivers impact protection in a wafer-thin breathable foam, perfect for a horse splint boot.
  • ThinLine doesn’t compress.
  • Pressure points; created from tendons, bones, splints, or wind puffs, are gently shaped into the ThinLine memory which rebounds once it is off the horse.
  • Additionally, an anti-microbial agent is infused into ThinLine allowing use on multiple horses.
  • ThinLine foam does not absorb water or collect dirt which means boots stay in place and are easy to maintain.

Pro Mesh Exterior Construction

Pro Mesh is used for the protective outer layer of our closed front splint horse boots. Pro Mesh material acts like a flexible horse armour, offering the ultimate combination of breathability with impact and abrasion protection as well as support and durability.

Additionally, Pro Mesh is engineered in a way that reduces the amount of stitching and glue required during boot assembly.

What is Pro Mesh Engineered Material?

Pro Mesh material is RoHS and REACH compliant. Directly injected into a strong but breathable fabric mesh the materials bond and become ONE and will not separate. No toxic glues are used.

Pro Mesh is extremely tough, strong, and conforms to shape allowing it to outperform fabric or leather boots.

Pro Mesh G3 was designed by SinoBlue specifically for equestrian boots. It uses a honeycomb hex pattern that reduces weight plus offers an optimum mix of protection, airflow, strength, and flexibility.

Cools and Protects

Designed to keep out grit and sand it helps guard against rubbing. Water-resistant, strong and protective, this closed front splint horse boot is designed to deliver support with flexibility, thereby maximizing joint movement.

Strong & Durable

Our technology focuses on equestrian leg protection needs. By combining materials using state-of-the-art tooling design and injection techniques synergy was attained between these materials.

ThinLine Pro-Mesh is the most effective and durable horse boot on the market. Your Flexible Filly Boots come with a one year 100% replacement product warranty. We recommend Flexible Filly boots for both riding and turnout.
