Adidas calls the Adizero Prime X Evo the “fastest long distance shoe” in history. It’s certainly the boldest.

As of this year, it is the only shoe to ever run under six hours across 100 kilometers, when South African ultrarunner Sibusiso Khubeka accomplished the feat at an Adidas-sponsored time trial called Chasing 100.

That said, records aren’t the only thing it breaks.

As noted by Adidas, almost proudly, the massive 50mm stack height sits outside of World Athletics regulations. But that’s probably besides the point.

It’s a concept shoe that puts Adidas on the front lines of innovation within running, simultaneously debuting technology bound to trickle down into more accessible trainers.

These include something the brand calls an Internal Energy Rim, a ring which replaces the EnergyRods found in its plated racers, as well as a dual-compound outsole that, quite literally, disappears underfoot.

It also tests runners’ tolerance for shoes built solely for performance, not scale. Released via lottery, the Adizero Prime X Evo cost $500 at retail, making it one of the sport’s most expensive, and exclusive, shoes … ever.
