Flexible Filly Closed Front Splint Boots

Wrap your horse in comfort with this lightweight breathable nonslip protective horse boot. These horse splint boots are great for horses and even better for owners. The low profile fit is only outdone by the ease of care for horse owners.

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. Also, an anti-microbial agent is infused into ThinLine allowing use on multiple horses.  Finally, 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 ‘flexible horse armor’ 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. It is directly injected into a strong but breathable fabric mesh. The materials bond and become ONE and will not separate. No toxic glues are used. It is extremely tough, strong and conforms to shape allowing it to outperform fabric or leather boots.

Cools and Protects

Pro Mesh G3 was designed by SinoBlue specifically to make equestrian boots. It uses a honeycomb hex pattern that reduces weight plus offers an optimum mix of protection, air flow, strength, and flexibility. 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 in a special way, using state-of-the-art tooling design and injection techniques, synergy was attained between these materials.

ThinLine Pro-Mesh, 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.

    I’ve had these a few months now. The are very soft and flexible on his legs but still have good strike protection. His legs stay pretty cool and we have had no rubs even though they are a tad long in the height for his legs. Easy on/off and they stay put. I’d buy them again.

    I bought these boots because I’m always on the lookout for lightweight splint boots. I’ve not been disappointed. These are the lightest boots I’ve owned so far, flexible and protective. Super easy to clean, I just wipe them down with a damp sponge. And because the boot seems to mold around my horse’s legs, arena footing and other crud doesn’t get inside and his legs don’t get super sweaty from wearing them. Highly recommend if you’re tired of the bulky, fleece-lined style of boots.

    Love these boots! I use these every day and they wash up great, dry fast, and look good on my horse as well as offering comfortable protection. Just ordered my second set!
