Thanks to Hypebeast, all of us can view a video of how the adidas Ultra Boost is assembled. While we wish we could see how the Boost midsole is made, the video does show how the Primeknit upper is constructed and how the shoe is pieced together. If you have never seen how a shoe is assembled, the above video is worth a view.
By now you’ve seen adidas’ new Boost midsole compound, designed to give runners a significant increase in energy return over a traditional EVA midsole while remaining soft and cushioned underfoot. Following through with the expansion of footwear options offering this new technology, adidas is introducing a racing shoe utilizing the Boost midsole, combining elements from the Energy Boost and the highly pedigreed adizero adios. It’s called the adios Boost. Coincidence? We think not.
With a soft yet responsive ride, and with cushioning that is designed to stay consistent as the miles rack up, the adios Boost sets itself up to be a strong choice for runners seeking a racing shoe for their next marathon. The adios Boost got its official launch at the Boston Marathon expo and over the weekend Emmanuel Mutai wore the shoe at the London marathon.
What to Watch For
- Seamless Toebox: Heat transfered overlays over the toe-box limit seams for reduced friction on the foot.
- Responsive Toe-Off: The adios Boost utilizes a full-length torsion system, delivering a snappy rebound for a propulsive toe-off.
- High Traction Outsole: Featuring Continental rubber in key areas, this shoe will provide unrelenting grip on the road in both dry and wet conditions.
- Midweight Specs: adidas claims weights of 8.0 oz for a Men’s size 9 and 6.6 oz for a Women’s 8, as well as a 10mm heel to toe offset.
It’s been a while since we’ve seen some revolutionary new running tech from adidas. But in the spirit of go ‘big or go home,’ adidas has just introduced a new midsole technology it claims will “change running forever.” There might be just a bit of hyperbole in that marketing message, but we think they’re onto something with the new Boost foam, which is debuting in several new running models this spring and fall.
If you follow the world of running footwear, you’ve probably stumbled upon this video demonstrating adidas’ new Boost material:
Comprised of small TPU pellets molded together, the Boost material promises significantly increased energy return over a standard EVA foam, while feeling even softer underfoot. The midsole is claimed to maintain the same density from mile 1 to mile 600 as well as in all temperatures. Don’t let the ‘packing peanuts’ look fool you – we’ve had a chance to give it a try and we found the compound to offer a surprising amount of rebound and responsiveness despite its soft underfoot feel.
