Up Hyper Air Tech

We reimagined the running shoe sole with 3D printing, creating our exclusive lattice cushioning technology that boosts energy return to 86%.
In the lab, it absorbs 40% more impact energy at 5 m/s than traditional foams; on the track, it helps reduce peak knee joint load by 15–20%.
This isn’t just a shoe—this is Hyper Air. Every landing accelerates you forward while taking pressure off the world.

Street‑Ready Trainer

Perfect for curb intervals, stair bursts, or a spontaneous park circuit. It’s the urban trainer that doesn’t slow you down.

Boost Training Performance

Reduces impact to protect your joints — move with less strain.
Responsive rebound that resists compression for long‑lasting comfort and support.
Conforms intelligently for even pressure distribution and retains its shape over time.
Air‑permeable materials deliver instant cooling to help you stay comfortable during activity.

FAQ


Get quick answers to common questions about Aero.

How should I clean the shoes if they get dirty?
What if foreign objects or pebbles get stuck in the lattice?

Use a high-pressure water gun to wash them out.
Can 3D-printed shoes be worn every day?

It is recommended to alternate between at least two pairs of shoes. Shoes also need to “rest.” When not worn for long periods, store them in a cool, dry place, away from compression and sunlight.
What environments should I avoid?

The shoe’s outer color is applied post-printing. Color fading may occur on the outsole or areas with frequent friction. This is a normal phenomenon and not considered a quality issue, and it does not affect product lifespan.
Will the shoes fade?
Will the outsole wear down?

The lattice outsole may show some wear after long-term walking. This is normal and not a quality issue.
