Badwater 135
Where the world's leading automobile manufacturers put their prototypes through their most intensive testing, that's where we put our running shoes under the toughest conditions!
Of course you can test new running shoe developments in the lab, like most manufacturers in the industry do. When it comes to our new developments, our aim is to test our shoes under the most extreme conditions possible. This is the only way we can ensure that they meet your requirements. That's why, after 2021, 2022 and 2023, this year we were the official shoe of the "Badwater 135" for the forth time in a row: at the legendary ultramarathon through Death Valley.
This year, the runners are testing our latest running shoe model, the Addict Pro-R.

Jedes Jahr kontaktieren wir, koordiniert mit Race Director Chris Kostman, das Elitefeld der Teilnehmer des „World´s toughest footrace“, dem härteste Ultramarathon der Welt.
Wir arbeiten mit einer Auswahl dieser Elite-Ultraläufer zusammen, um ihnen den aktuellen Stand unserer Prototypen und neuesten Entwicklungen zur Verfügung zu stellen, so dass diese auf Strecken und unter Bedingungen getestet werden, die in keinem Labor der Welt nachgestellt werden können.
Die Läufer teilen nach dem Rennen ihre Erfahrungen detailliert mit uns, so dass diese kontinuierlich in unsere Weiterentwicklungen mit einfließen können.

"I trained a bit with the shoes and felt pretty good with them. I definitely like that they give me a lot of toe room."
Doug Strong (wore the shoes as a pacer for around 40 hours at a time throughout the Badwater Ultra)
"All this (points on the forefoot of the shoe) is just freedom and support and than here (points on the heel area) it hold you like a normal shoe!"

Bobby Seeberger, ultramarathon runner and Badwater 2022 finisher (wore the shoes from mile 17 to mile 102).
"I love these shoes! I can't wear a shoe right out of the box. I usually bring two to three pairs. At mile 17 I just said "give me those shoes" - they are just great! I don't have fat pads on the ball of my forefoot anymore - it's like skin on bone. To get a shoe that don´t hurt right there - it's a miracle!"

"Bobby really has problems with his feet. He usually loses three to five toenails during a race. After 80 miles, his nails look good thanks to the wide toe box of the Ultreya®. He usually switches back and forth between several brands during a race because his feet hurt. So he gets three to four pairs per 100 miles. Today is different. At mile 17 he put on the Ultreya® and has been super happy ever since!"
Marc Siques Llagostera, Badwater Finisher 2022 and ultramarathon runner
"The shoe is very comfortable and well cushioned. And this feeling does not disappear when you walk in it for a longer time. Thanks to its wide toe-box, it gives you a stable walking feeling. And you appreciate that when you walk in it for many hours. (...) I would definitely recommend the shoe. And if I find it in a shop in Spain one day, I will try it again. The one I have now has already done a lot of kilometres."
When the boss spontaneously turns into a Badwater runner
In the end, Sebastian couldn't stop himself. He wanted to personally experience how it feels to run in the Ultreya® on hot asphalt in maximum heat. He obviously didn't make it all the way to the finish line (of course, just because of a Corona infection the week before). But together with the renowned biomechanic Lee Saxby, he evaluated the aspects of biomechanics, their influence on sole design (uphill and downhill) as well as breathability and much more under these extreme conditions.
