Inside the shoe
Heel and forefoot sit at the same height, keeping the foot level for a natural posture and a midfoot landing.
Around 28 mm of foam gives balanced protection for daily runs and quicker sessions without losing feel for the road.
At around 223 g it is light enough for faster efforts yet comfortable for easy everyday miles.
The insole lifts out so you can fit your own orthotics, and rubber covers the main wear zones.
