RE-ENERGY SYSTEM Technology

The patented Natch! RE-ENERGY system returns energy to the foot during the push-off phase:

Impact phase: Insole absorbs kinetic energy upon landing
Stance phase: Anatomical structure distributes pressure evenly
Push-off phase: Elastic material releases accumulated energy for propulsion
Result: 3-5% less muscle fatigue over long distances, 2-3% improved stride efficiency

Who It's NOT Suitable For

❌ Avoid this product if:

You are looking for a corrective orthopedic insole for severe foot problems (requires medical prescription)
You need maximum pronation support (this is neutral)
You prefer an ultra-cushioned gel-type insole (this is performance-oriented)
You only run short distances <5km (overkill, a basic insole is sufficient)

Frequently Asked Questions

Does the RE-ENERGY SYSTEM really work?
Yes, independent tests show a 3-5% reduction in fatigue and a 2-3% improvement in stride efficiency over distances of 20+ km.

Can I use it for daily walking?
Yes, but it's oversized. For normal walking, a standard comfort insole is better; this is for performance running.

Is it suitable for pronators?
For mild-to-moderate pronation, yes. For severe pronation, a specific corrective insole or stability shoe is needed.

How long does it last?
600-800 km or 6-9 months of intensive use. Signs of replacement: loss of elasticity, visible wear, reduced comfort.

Is it trimmable?
Yes, follow the guidelines printed on the insole to perfectly adapt it to your shoe.
