How long does cushioning last?
How long does cushioning last?
We have excellent durability due to our supercritical foam HyperBolt™. We recommend 300-500 miles of wear before looking to replace them for another. Read our durability guide to get more from your shoes.
What does a neutral shoe mean?
What does a neutral shoe mean?
Neutral pronation is when the foot rolls inward about 15% after landing to absorb impact, while overpronation occurs when the foot rolls inward excessively (beyond 15%), causing the arch to flatten and potentially leading to various foot and leg problems. A neutral gait is more common and this is what the IMPACT is built for.

HYPERBOLT™
Our supercritical soles are gas injected with Nitrogen and bio-based EVA reducing density, enhancing responsiveness and creating an unprecedented blend of soft landings and fast take-offs.
TREADLIGHT™
Our grip technology is inspired by racing tyres and their ability to displace water and increase traction. The cutouts between the rubber pods reduce weight and increase ground contact when wet.
CLEANTECH™
Outpacing synthetics with renewables. The IMPACT is crafted with bio-based materials like castor beans that mimic the performance of their synthetic, fossil fuel derived counterparts. All whilst creating less carbon footprint per stride.
