In 2014, reports said inventor Keahi Seymour’s experimental Bionic Boot prototype could reach 25 mph (about 40 km/h). That figure was a reported prototype claim—not a speed documented by independent testing in the coverage. The boots were an ambitious design shown at World Maker Faire, not an established consumer product.
What were Keahi Seymour’s Bionic Boots?
The Bionic Boot was an experimental running device developed by inventor Keahi Seymour, inspired by the springy gait of ostriches. Popular Science reported that Seymour had made multiple prototypes and demonstrated the then-current version at World Maker Faire in New York in 2014.

The public demonstration established that a prototype existed; it did not establish that the device was a finished or commercially available boot.
Could the boots really make someone run 25 mph?
Futurism attributed a speed of 25 mph (about 40 km/h) to the prototype, and Popular Science also reported the figure in 2014. Neither article describes a timing method, controlled trial, or independent measurement. The careful answer is that 25 mph was reported as a prototype capability, but the reviewed coverage does not verify it as a measured result.
#1 Best Overall
- Athletic mesh upper with durable leather overlays for added dimension & midfoot support
- Charged+ midsole cushioning provides unmatched softness & all-day comfort
- Durable rubber outsole provides traction & durability with strategically-placed flex grooves for proper toe-off
- Upper contains at least 30% recycled content
- Weight: 10.2 oz , Lace type: Standard tie, NEUTRAL: For runners who need a balance of flexibility & cushioning
Popular Science also reported that Seymour hoped eventually to reach 40 mph. That was a future target described in 2014, not a demonstrated speed.
How were the boots supposed to work?
Futurism described springs at the rear of the boots as an attempt to imitate the spring-like action of an ostrich’s Achilles tendon. The proposed mechanism was intended to add downward force during running. The article provides no engineering measurements that quantify how much force the springs generated or how they affected a runner’s speed.

Are the Bionic Boots for sale or safe to use?
The 2014 coverage describes a prototype and does not establish a retail product or present-day availability. Futurism said Seymour was still working toward a fully functioning boot. The articles also provide no price, consumer operating instructions, safety testing, or injury evidence. Their account is not a basis for treating the device as safe for consumer use.

What the 2014 reports establish
- Seymour developed an ostrich-inspired experimental running device and showed a prototype at World Maker Faire in 2014, according to Popular Science.
- The 25 mph (about 40 km/h) figure was reported as a prototype capability by Futurism and Popular Science; the articles do not document independent verification.
- The rear springs were described as part of an ostrich-inspired design, but the reporting gives no quantified engineering results.
- The coverage does not establish a finished consumer product, current availability, or consumer safety.
