Updates to Nike Flex RN 2015

  • The 2015 version of the Flex RN from Nike is a definite step up when it comes to design and appeal. Utilizing a more contemporary frame of look, this running shoe does well as a sports shoe and as a casual shoe. Even the subtle overlay design has a honeycomb shape to it. It’s a solid option for daily running and casual walking.
  • The Breathe Tech upper unit technology makes sure that the upper is able to wrap the foot snugly, securely yet comfortably at all times. The breathable materials used for this unit make sure that the foot stays dry and cool in any activity.
  • The midsole unit features lightweight foam components that carry the foot well through the gait cycle. It delivers efficient underfoot cushioning and overall comfort that’s ultimately responsive to the natural movement of the foot.
  • Durable rubber is placed in critical areas of the outsole where it’s most capable of holding back wear and tear. Flex grooves throughout the sole unit make sure that the runner experiences an unrestricted and consistent range of motion.

Nike Flex RN 2015 size and fit

The Nike Flex RN 2015 is true to its size. It’s available in a variety of sizes that adhere to what the runners are most accustomed to. It has a medium width when it comes to its heel, mid-foot and forefoot areas. It can accommodate feet with narrow-to-medium dimensions.


The outsole unit of this running shoe makes use of a high quality rubber. It’s placed in sections of the external sole unit where wear and tear are most commonly observed. They offer durable protection from abrasion, as well as traction for better control over the roads.

Full length flex grooves make sure that the outsole is able to provide maximum range of motion for the wearer. This design actually goes well with the pliable and soft nature of the foam cushioning to enhance the flexibility of the runner.


The Phylon mid-sole is a lightweight foam that’s responsive, but not very thick. This low-profile cushioning system delivers responsible cushioning, as well as additional pressure mapping to improve the comfort that the foot experiences.

The two-piece Phylite carrier encourages natural movement. Separated near the forefoot, it gives the front section of the foot more incentive to move freely, especially when handling toe offs and forefoot bending. It also reduces the bulk of the sole unit.


The mesh material that’s used as the main component in the upper is comfortable and breathable. It offers a well-ventilated coverage that keeps the foot cool and dry because its open construction actually encourages air to seamlessly enter the shoe’s interior.

The Breathe Tech system in the upper uses mesh and foam, which keeps the foot in a comfortable and supportive wrap. It’s a snug feeling, but not too tight as to feel uncomfortable.

The overlays that were used in the Nike Flex Run 2015 are minimal and they aren’t stitched onto the upper unit. The seamless design reduces skin irritation and encourages sockless wearing.

The sock-liner that’s used for this model is made from Ethylene vinyl acetate, which is a durable material that gives additional cushioning, as well as shock attenuation for a smoother ride.
