 Cobra Support Horse Boot – Sports medicine style gets a huge upgrade with a breathable, supportive ThinLine interior.

Close Out Boots-Can not be returned for refund

Why ThinLine boots?

  •  The only closed front SMB boot lined with ThinLine protection
  • – When ThinLine warms to body temperature it molds perfectly to the horses’ leg. When below 89 degrees it returns to its original shape.
  • – ThinLine does not absorb water so boots won’t shift or rub
  • – Infused with Anti-microbial agents to prevent skin problems and allows use on multiple horses
  • – Ventilates to keep tendons cool
  • – Dirt will not stick to the ThinLine lining making them super easy to keep clean.

Our ThinLine Cobra Boots look the same on the outside, but it is the breathable, no rub, easy care lining that will change your riding world!

ThinLine vents heat so tendons stay cooler. Infused with USDA approved anti-fungal agents to allow for use on multiple horses. Cobra support boots for horses are extremely slim compared to traditional Sport Medicine Boots, horses look neat and well turned out. The favorite boot of reining riders like Mike McEntire and Jon Ingram, this boot protects, holds up and gives you a much cleaner look in the show ring. It is easy to care for and is far more durable than its full neoprene competitors.

The exterior ventilated neoprene conforms to your horse, allows heat and moisture to escape, and keeps your horse cool, comfortable and performing at it’s best. Fully lined with amazing ThinLine foam, the support boots for horses provide 360 degrees of protection, safeguarding the cannon bone, tendons, and soft tissue. Proven to absorb energy from hoof impact. The uniquely designed suspensory strap stretches with each stride, allowing full ankle movement and helps eliminate hyper extension of the fetlock.

Most importantly, horses love them!  Comfort is key in performance!  Cobra support horse boots are sold in pairs (one for the left leg, one for the right leg) Sale pricing, no returns.

    These SMBs are great. A couple horses that I train and compete go in these boots. I love that the inside has ThinLine to absorb shock and also because it is so easy to clean out. Hair, mud, sand, doesn’t stick to the inside of the boot. Plus, they are comfortable on my horse’s legs. Also, the white looks really flashy 🙂

    “So today ThinLine Cobra Sports boots saved Ozzy’s leg.
    Thank you David Cowley for encouraging me to always boot your horse. Ozzy was 2nd heading into the final extreme cowboy round. In the finals we hit the last jump really hard. It broke through the neoprene but the ThinLine impact foam stayed intact, did its job and saved Ozzy’s leg. Ozzy is totally okay and ended up 5th at his first race…and I got a new cowboy hat!” – Lindsey Partridge.

    “I own Polocrosse Gear, and carry a variety of ThinLine products. But, not only do I sell ThinLine, I also use it! Now, we all know how great your saddle pads are, but I really love your protective leg-wear! I can’t say enough about how nice the medicine boots are. They have held up so much better than many of the other name brand boots I’ve used. What’s better to me is that they don’t get heavy with water, and the material somehow keeps my horses’ legs cool. With other brands, when taking the boots off, their legs are hot and sweaty. I also use the tendon boots- perfect fit and durable to give added protection out on the field. THANK YOU ThinLine for keeping our horses’ safe and comfortable.” – Sarah Evans Dancsisin

    I ride cutting horses and I don’t think anything comes close to the Thinline Cobra boots for protection, heat dissipation, and comfort of the horse. I just wish they made the Cobra with a skid pad for the hinds. Outstanding product.

Questions and answers of the customers

  1. A Thank you for your question! These boots are sold in pairs.
  2. A Thank you for your question! The Cobra Boots are essentially a rectangular shape with velcro closures and a longer, stretchy strap that wraps around the fetlock. The measurements shown in the sizing tab at the bottom of the page refer to the longest points of that rectangle, top to bottom, and side to side where the boot will wrap around the fetlock. We recommend measuring those places on your horse's leg or on a well fitting pair of boots you already own and compare with the measurements in the sizing tab.
  3. A Hi and thanks for your question! Yes, for hinds of this boot, you would just order the next size up.
