These lightweight, low-profile shoes encourage a natural stride. The unique one-piece, concave shape of the outsole is designed by ultramarathoner Scott Jurek. When force is applied, the sole splays out to provide a balanced lay-down and a ground hugging feel.
- Uppers are breathable mesh and foam. An elastic wrap over the instep provides a comfortable fit for any foot shape
- Midsole is BioMoGo® copolymer foam that offers substantial cushioning and rebound with a long lifespan. It's injected with a non-toxic additive that allows the foam to breakdown faster than EVA in anaerobic landfill conditions
- Anatomically shaped heel and forefoot inserts are incorporated into the midsole in high impact zones to improve cushioning and rebound
- Highly viscous fluid (looks like a gel) remains loose and flexible under low impact conditions, but provides a strong, supportive platform during foot strike
- Toe Flex® technology has a split between the toes to enhance forefoot flexibility. It allows the big toe to engage for stability and a powerful push-off
- Ideal Heel® (inverted heel) encourages contact points to shift forward to align joints and allow good energy return
- Outsole is one-piece with a concave shape that splays out to provide a balanced lay-down. Grippy, sleek lug pattern and a wide base to protect your feet
