Why runners love Kila

Shoes are mass-produced and sized only for length and width. If you have high arches, flat feet, or poor running form, pain and injury are almost inevitable. Custom insoles rebalance your feet and turn your shoes into an extension of your body. This means: less pain and fewer injuries—from the hips down.

Getting custom insoles (orthotics) at a podiatry or sports med clinic means paying $500-$2000+ They charge a markup because they can. We use their same lab and iPhone scanning tech, but let you scan at home. This saves you the hassle of visiting a clinic and also $$$.

We’re the first custom insoles built specifically for running performance. Kila insoles are flexible (allowing all three phases of gait), lightweight, and made with super shoe materials to maximize forward bounce. With precise arch-to-arch contact, they improve power transfer and help the big toe joint engage faster—significantly enhancing propulsion.

Performance materials

Lightweight. Maximum bounce. Durable.

Dura-Swiss top cover

Our medical-grade top cover will outlast and outperform any off-the-shelf insole. Since each insole we produce is entirely unique in shape, our lab techs custom-trim each top cover individually—like handmade shoes from a cobbler. This results in a seamless edge finish, eliminating any gaps or potential for rubbing.

FASTec Filament

Custom 3D extruded insole body using our proprietary FASTec filament. The lightest, most flexible, and highest energy return of any orthotic/insole structural material on the market.

Adaptive and Dynamic Support

We found, through countless hours of testing with a variety of support structures, that having variable support structures allowed for a better fit. No one-size-fits-all solution.

With 3D printing, we're able to do things that mass-produced insoles could never dream of. Compared to EVA foam (the industry standard for custom orthotics dating back to the 1970s), our dynamic hex beats it in every category—weight, strength, and longevity—while also adaptively changing firmness in critical regions.

The Tech

Why custom running insoles?

Years of pounding the pavement adds serious stress to your feet, knees, hips, and legs. That repetitive impact, over the course of thousands of miles, eventually takes its toll. If you're not landing in a balanced or neutral position, injuries will keep coming back and slow your progress.

Kila insoles give you the support to land correctly, significantly reducing strain and improving alignment from your feet to your hips. Similar to running on sand, perfect arch-to-arch contact redistributes impact from the bony areas (heel and ball) into the soft tissue of your arch—where your body is designed to absorb it.

Most shoes are built around a generic foot shape, which means force is still concentrated in hot spots in the heel and ball—regardless of your form. Big shoe brands logistically can't offer enough 3D footbed variations in their shoes because it would require thousands of size combinations for each model. That’s where Kila comes in.

Kila custom insoles help:

  • Relieve foot pain
  • Prevent injury
  • Treat plantar fasciitis
  • Improve mechanics and form
  • Optimize support and alignment

Clinical orthotics are rigid. They provide support—but at the cost of proper foot mechanics. As die-hard runners, we couldn’t believe no one had built an insole specifically for running performance. That’s why Kila insoles are flexible, allowing for all three phases of gait. With perfect arch contact and a zero-drop structure, we can get the big toe joint down faster—which directly increases propulsion.

Performance Benefits:

  • Increased propulsion
  • Maximum power transfer
  • Faster recovery
  • Less pain = better training

And using prefab insoles (the ones from the running store) is like wearing someone else’s prescription glasses—likely not helpful, and often worse. We build insoles that match your exact foot shape down to the millimeter—not just increasing comfort, but giving you better alignment and turning your shoes into an extension of your body.

Fun fact: Your feet are siblings, not identical twins. That’s why we craft two unique insoles—one for each foot.
