Unisex Axis Running Shoe

Hylo's own summary of the Axis is naturally stable, and that word order matters - this is a shoe that guides rather than corrects. There is no medial post and no hard plastic. Instead a broader platform, a sculpted midsole geometry Hylo call PureGlide SP, and a slightly denser foam do the work between them, so the ride feels supportive without ever telling your foot where to go. Underneath it is a deep bed of HyperBolt+, their nitrogen-injected foam, which is what makes a stability shoe this soft.

The other half of the story is what it is made of. Hylo build the Axis from bio-based and recycled inputs throughout - the upper knit comes from castor-bean yarn, the lining from corn, the outsole is mostly natural rubber, and there is even seaweed in the mix. Their framing is higher energy return with a lighter footprint, and the useful part is that none of it reads as a compromise: the upper is a structured warp knit with zoned breathability and a reinforced heel counter, which is exactly what you want holding your foot over a long run.

Hylo Athletics was founded on a straightforward frustration: running shoes are made almost entirely from plastic, and almost none of them get recycled. Hylo builds performance shoes from bio-based and recycled materials instead — supercritical foams grown from plants, natural rubber outsoles, uppers engineered to hit 50% bio-based and recycled content — and refuses to trade away weight or energy return to do it. At Mountain Sports, we love Hylo because it proves the trade-off was never real: a genuinely light, genuinely bouncy daily trainer that happens to ask a lot less of the planet.
