Do you all remember the Nike Shox when they came out? Yes, the ones below.

At the time, they were revolutionary and everywhere. They also ran you $160, which seems crazy given it’s now 2026 and truly game-changing footwear still costs about the same.

The 2026 On Cloudmonster 3 Hyper LS is not the Nike Shox of 2000. But it might be just as revolutionary, for the opposite reason.

The Shox got hyped because you could see the tech — those visible springs were basically a billboard on your foot. LightSpray is the opposite play. On built a shoe where a fleet of robots spray a single filament directly onto the midsole, forming a seamless, laceless upper in about three minutes. No stitching, no cutting, no dozens of separate upper pieces glued and sewn together by hand. Just one continuous piece of material shaped exactly to the foot it’s going on.

It’s a completely different way of manufacturing something and it’s On rebuilding how a shoe gets built from the ground up, and they’ve committed to it hard enough to open a factory in South Korea dedicated entirely to LightSpray production. This version also brings Helion HF, the foam from On’s actual race-day supershoes, into a plate-free trainer for the first time — so it’s not just a party trick upper bolted onto a normal shoe.

These are not going to be sitting on a shelf at Dick’s or Foot Locker anytime soon. It’s expensive to make, harder to scale, and On knows it. Which is exactly why we wanted to take them for a Snack Run and discuss just how they feel on the feet.

Check out the video above to just hear what we had to say, and what convenience store snack we compared them to.
