This is the new generation of Currex insoles - 7% lighter than the older model, with more dynamic arch support. The insole is slightly firmer to provide more stability but still responsive & flexible enough to move naturally with your foot. Suitable for running, jogging, walking, triathlon, or everyday life. Giving the arches support they need, these insoles will help to improve your performance. You'll experience less fatigue in your feet and calves and get extra protection and propulsion thanks to the heel and forefoot gel pads.
