Elevate your running performance and smash your personal best with the upgraded Bmai Jindouyun 2.0 Supercritical Racing Insole. Engineered with industry-leading supercritical foamed TPU, this premium running insole delivers explosive energy return, ultra-lightweight cushioning, and blister-free comfort for marathon racing, speed training, and daily road running.
The Bmai Jindouyun 2.0 is our fully upgraded high-performance racing insole, purpose-built for competitive runners and everyday athletes seeking to unlock the full potential of their running shoes. Replacing lackluster stock insoles, this insole combines cutting-edge supercritical foam technology with ergonomic design to reduce fatigue, amplify your stride, and keep your feet comfortable mile after mile.
At the heart of the Jindouyun 2.0 is our proprietary BoomFly supercritical foaming process, creating a high-performance TPU core with an ultra-low density of just 0.085g/cm³, a Shore 25C hardness for plush cushioning, and an 80% ball rebound rate for explosive energy return with every step. This advanced material maintains consistent performance even after hundreds of kilometers, with minimal compression set for long-lasting anti-fatigue support during marathons and long training runs.
We’ve boosted cushioning without adding extra weight: the 5mm forefoot and 6.5mm heel thickness absorbs road shock and reduces joint stress, while a single insole (size EU 42) weighs just 15g — lighter than most competitive racing insoles on the market. This zero-burden design ensures your insole never slows you down, whether you’re sprinting for the finish line or logging daily training miles.
Engineered with 3D molding technology, the Jindouyun 2.0 features a contoured arch support structure to stabilize your foot and reduce arch fatigue during long runs. The laser-cut forefoot and low-profile edge design eliminate curling and slipping inside your shoe, drastically reducing friction, hot spots, and blister risk during high-speed racing and extended training sessions.
The upgraded soft brushed top fabric is skin-friendly, moisture-wicking, and highly breathable, keeping your feet dry and cool throughout your run. It specifically targets the common runner pain point of sole burning sensation during long-distance runs, delivering consistent comfort from the first mile to the final sprint.
