The Feidian 6 Ultra is built around a four-layer performance stack engineered for race-day speed. At its core, the Super Boom Capsule midsole delivers ultra-fast response with an energy return rate of up to 95% and a reaction time as low as 3ms.

A T1000 full-length ballistic carbon fiber plate — running a dual-arch structure — stiffens
the forefoot and drives explosive propulsion with every stride. The Dual-Stage Assist Curves geometry accelerates both heel-strike and toe-off, keeping momentum continuous throughout the gait cycle.

Underfoot, the next-generation GCU Ground Control Unit features a net-structure thin outsole with multi-angle interlocking grip, engineered for traction, durability, and confident footing across varied surfaces.

  • Four-layer midsole power system: Super Boom foam upper layer, Super Boom Capsule mid-layer, Li-Ning Jiang Carbon-fiver plate, dual-stage assist curves lower layer.
  • Li-Ning Boom Fiber upper with 35% improved breathability vs. traditional mono-yarn.
  • Super Boom Capsule with 3ms response time and 95% energy return rate.
  • Biomimetic wing-shaped fiberglass support plate for torsional resistance and arch stability.
  • Support plate with widened forefoot-to-heel design for balanced, stable landing.
  • Full FOS Knit Upper Breathability increased by +117.6%

  • Tear-resistant upper construction that stays secure and breathable through long runs.
  • Next-generation GCU Ground Control System outsole for grip and abrasion resistance.
  • Suitable for road, track, and wet surfaces across high-frequency training use.

Don't buy doesn't work
Style: 18oz, Style: 18oz
Terrible did nothing. Even tried to let wheel turn 360 degrees yet the solution get in the tire leak proper. Directions on can differ from instructions on here/Amazon. I followed directions on can EXACTLY and still didnt even hold one PSI of air. I'd be better off burning the $10 for warmth rather then waste it this way

Amazing stuff
Style: 14oz
I’ve been using this stuff for a number of years for a number of vehicles now and it works every time. It’s especially great with those small annoying leaks where you just lose a couple pounds every few days so you have to keep adding air like once a week. It totally seals it. The bottle says to only rely on it for 300 to 500 miles and then get a proper fix. However, I have not found this to be the case. The seal holds for the rest of the life of my tire every time I’ve used it. My only complaint is that I wish it was a little cheaper, but you can seal up 2 tires (use only half the can per tire - you can probably even get away with using less). There is a garage not far from me that fixes leaking tires for $10, which is the same price as this product so not really saving any money by using it. It’s more just a matter of convenience. Just make sure you get this “thru-core” one. They have other ones as well so it can get confusing, but the one you’d want for situations like I’ve described above (small to medium leak in a typical passenger vehicle) is this “thru-core” one.

Saved the day, even at 25°
Style: 18oz
The tire tread was peeling off the tire causing a leak that could not be plugged. Completely flat. It was about 25° outside and the can only dispensed half the contents. Was able to inflate the tire and make it to the shop. So the slime saved the day.

Awesome product. Very easy to use repaired my tire with no issues. It’s a very compact kit. Great price. The plug has proved to be durable as I’ve been driving the car with no leaks or issues.
