Show Description

A single pieces of fabric forms the upper, so these road shoes mould to your feet like a second-skin. The 4.0 rating means they fall toward the barefoot end of Nike’s classic-to-minimalist continuum, allowing natural movement while providing support and protection as you built strength.

  • Flyknit uppers are a single-piece of ultralight polyester that's incredibly strong, and has less waste than traditional cut and sew construction.
  • Ultralight Flywire cables woven into the uppers connect to the laces, for supportive fit that follows your foot's movements.
  • Midsoles are cushioning, supportive phylon, siped to allow foot strengthening flexibility.
  • Hot knife siping on the soles to promote natural movement and provide additional flexibility.
  • Outsoles have rubber pistons for cushioning and a rounded anatomic heel.

Ideal for Road 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.

Closure Lace-up
Heel-to-toe cushioning

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.


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.
