Insoles for running

Give back 14% more energy, mile after mile

The insole your running shoes ship with packs flat within a few hundred miles — you lose cushion and energy right when your legs need them most. Blumaka's reclaimed ETPU foam springs back instead, returning 14% more energy on every step and holding its cushion for about 1,000 miles.

The problem

Why do your legs fade early in a run?

It starts with the insole your shoes ship with — a thin foam layer that packs flat within a few hundred miles. Once it's crushed, it stops giving energy back and stops absorbing impact, right when the miles start to add up.

  • Thin foam packs out fast — the bounce is gone before your shoes are.
  • Less energy returned means more effort on every stride.
  • Worn-down cushioning means pounding, fatigue, and sore legs late in a run.

The fix is Blumaka's reclaimed ETPU foam — it springs back instead of packing flat, so you get more energy return and cushioning that lasts.

Got questions?

Straight answers.

Do Blumaka insoles really add energy return? +
Yes. In independent testing the reclaimed ETPU foam returned 14% more energy than a standard insole and added 17% more cushioning. Because the foam springs back instead of packing flat, you keep that bounce deep into a run.
Which insole should I choose for running? +
For most runners the NonSlip Performance Insole fits running shoes well — pick your arch height (low, medium, or high) to match your foot. Road runners who want a lighter feel can choose the Performance Insole.
How long do they last? +
About 1,000 miles — roughly the life of a pair of running shoes — and they outlast three to four pairs. Every pair is backed by a 90-day performance guarantee.
Will they fit my running shoes? +
Yes, most. Choose from three arch heights and trim along the guide lines to match your size, using your shoe's factory insole as a template.
Do they help with foot fatigue and sore legs on long runs? +
The added cushioning and energy return reduce the pounding that builds up over distance, so your legs stay fresher late in a run.
Are they good for trail as well as road? +
Yes. The grip layer and cushioning help on uneven ground; choose the arch height that matches your shoe volume.
