- The Nike Free RN 2018 Sun is a running shoe that’s designed for the neutral pronator. It has a lightweight and flexible build that’s meant to accommodate the natural movement capacity and bending prowess of the human foot. Even its name suggests freedom to move and have control over the pavement.
- A knitted material serves as the fabric of the upper unit. Its purpose is to stretch and acclimate itself to the dimensions of the foot, thus giving a customized and agreeable wrap. Nike’s proprietary Flywire cables connect to flat laces, permitting the façade to hug the foot properly in tandem with the tightening or loosening of the lacing system.
- Underfoot cushioning is given by the Phylon midsole foam. It is a full-length unit that is exposed to the ground. Textured sections on the external part of this ground-contact material are responsible for surface grip.
This special edition of the Free RN 2018 is true to size. It welcomes the usual expectations of consumers when it comes to length. The width profiles of this model are D – Medium for men and B – Medium for women. The semi-curved shape of this running shoe allows the natural curve of the human foot to acclimatize to the in-shoe experience.
The outsole unit of the Nike Free RN 2018 Sun makes use of a full-length foam that is wholly in contact with the ground. It has a textured surface to dole out traction over the asphalt.
The Tri-Star construction is a set of three-pointed holes that make the underfoot platform flexible. They also reduce the overall weight of the foam. Such a design permits the natural capability of the foot to bend as it goes through the gait cycle.
Sipes are patterned across the sections that are more inclined to flex. These tiny cuts are meant to heighten the sole unit’s ability to follow the motion of the foot.
Phylon is a proprietary compound that’s meant to provide responsive cushioning to the foot. It runs the entire length of the Nike Free RN 2018 Sun, ensuring full coverage. Its flexible design leads the runner towards a smooth heel-to-toe transition.
A foam insole is placed right above the primary cushioning platform. It adds a bit more support for the underfoot. It can be removed or replaced with a different insert.
A knitted fabric graces the upper unit of the Nike Free RN 2018 Sun. It is breathable and stretchy. It aims to provide a form-fitting coverage that’s also well-ventilated.
A soft fabric lining has the goal of hugging the foot and keeping it free of irritation. Its smooth nature also allows the runner to wear this shoe without putting on socks first.
A stretchy heel lock system is made up of a wraparound spandex cover on the heel collar. It’s designed to secure the back of the foot in place, preventing it from wobbling or exiting the foot-chamber unexpectedly.
Dynamic Flywire cables connect to the traditional lacing system via parallel eyelets. These wires jut out from between the exterior and interior layers of the upper unit, adjusting the fit in conjunction with the tightening or loosening of the shoelaces.
The padded collar and the stretchy tongue offer support to the instep and the heel, respectively. These parts of the shoe are also responsible for maintaining in-shoe steadiness.
