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.
|Ideal for||Trail running|
Some shoes include added motion control or stability features to help minimize pronation or supination, where the foot tends to roll inward or outward in a biomechanically imbalanced running position.
The approximate thickness of the midsole cushioning under the heel and the forefoot. A thicker heel and greater difference between heel and toe height tends to suit heel-strike runners, while forefoot and midfoot strikers may prefer a minimal drop between heel and toe cushioning.
|15 - 11mm|
The drop is the difference in height between the heel and the forefoot midsole cushioning. Traditional running shoes tend to have a 10mm drop or higher while minimalist style shoes are on the lower end of the spectrum.
Waterproof shoes and boots feature a waterproof-breathable membrane and a gusseted tongue to help keep your feet dry in wet conditions.
