    The women’s Flex Run shoe from Nike will appeal to a wide range of female runners. It offers a lot of comfort and is ideal for those that have suffered discomfort in their feet, ankles and/or legs with their previous shoes.

  • Nike applies most of the changes in the upper. First important change in the upper is the new open mesh that really enhances the breathability of the shoe.
  • Another major change is the introduction of the Flywire cables that are directly connected to the midsole and the laces. A quick tug of the laces and runners can get their most comfortable fit and midfoot security with this technology. Nike uses a very unique design as the cables are clearly visible from the outside and keeps the air flowing.
  • The midfoot saddle is substantially thinner than before to give way to the Flywire cables. With the saddle and the cables, there is a really secure feel and support in the midfoot coming from the Flex Run 2014.
  • A slight makeover happens in the outsole as well. The tip of the forefoot and the crash pad are filled with small hexagonal lugs to add traction to the shoe.

The fit of the 2014 Flex Run is very similar to the previous model with the main difference being the snugger midfoot. Fans of this line should still be able to enjoy the average fit in the heel and the forefoot. Runners with narrow to medium feet dimensions should be very comfortable in this shoe. Medium is the offered weight while sizing is spot on.

The outsole is made of Phylite material, which Nike labels as 60% Phylon and 40% rubber and injection-molded. It allows Nike to save rubber and keep weight at a minimum. Nike covers this Phylite material with durable carbon rubber. There are hexagonal lugs that are evenly spaced for improved traction.

Phylon, a compression-molded EVA and rubber, runs the length of the shoe for consistent cushioning and smooth transitions. The lightweight nature of the foam belies its softness and responsive feel. This light material is also used in the midsole of the Nike Downshifter 7.

The minimal upper is characterized by an open mesh that delivers exceptional breathability. A thin midfoot saddle helps the Flywire cables provide unbelievable midfoot hold. These cables directly run from the midsole and looped with the laces. The tongue and collar have decent padding. A lace-up closure fastens the shoe.
