The Flyknit sock-like material and the two buckle straps in the Nike Air Sock Racer Ultra Flyknit has helped a lot in the shoe having a perfect fit that runs true to size. Shoe size comes in medium and ranges US size 6 to 14 in men and 5 to 12 in women.

Keeping a minimalist tone since its release in the 1980s, the Nike Air Sock Racer Ultra Flyknit has retained this noteworthy theme to much acclaim by many critics. Initially, NikeLab released a version of the iconic sneakers with fewer premium materials and with a huge Swoosh logo at the forefront which was literally panned by many shoe critics.

With the newer design in 2017, the Nike Air Sock Racer Ultra Flyknit removed that annoying Swoosh and kept is subtle at the heel back with minimalist branding. What really hyped up its style are the two suede leather straps that, although not really helping much in securing the feet,  has made the shoe look really cool for a minimalist tech-wear lifestyle sneaker.

The improved Flyknit material on the upper and the Air-Sole unit on the sole are two of the most notable features of the Nike Air Sock Racer Ultra Flyknit.

The Ultra Flyknit material has been a groundbreaking upper material for the multibillion-dollar brand when it was first released. The material helps keep the feet snug with its sock-like woven material that blends well to the contours of the feet. The Flyknit material also remains breathable, supportive, and lightweight making the shoe an ideal summer wear.

Meanwhile, the full-length Air-Sole unit has a round sipe pattern that features a dual-density foam midsole and a Free-inspired outsole with flex grooves. This superior sole technology helps make every stride count with lightweight cushioning and flexibility in tow.

“The Nike Sock Racer. A serious racing flat with a full-length Nike-Air midsole. Definitely not for everyone.”

This was a quote from the ad from Nike way back in 1985 during its initial launch and eventual release in 1986 that brought into sneaker consciousness the Nike Air Sock Racer. It was definitely not for everyone but it drew a huge cult following especially among serious runners and marathoners.

Designed by veteran shoe designer Bruce Kilgore, the same creative genius behind the Nike Air Force One and the Air Jordan 2, the Nike Air Sock Racer were running shoes that felt like wearing socks but could run full-length marathons.

Made of extremely breathable and form-fitting mesh upper, a Nike Air-Sole unit in the middle and lightweight polyurethane sole that are secured by straps and buckles for a quick fit, became Nike’s first running shoes kicks without shoelaces. It was also originally designed for marathon running as it promises to withstand 26-mile runs with ease.

Future releases of this shoe paved the way for modern designs such as the popular Nike Ultra Flyknit Racer.

In 2017, this iconic running kick was given a new treatment more than 31 years since it was launched with the stretchy upper with the introduction of Ultra Flyknit material that has kept many sneaker fans glued.

Flyknit is a result of a complex process of precision knitting that reduces as much as 60 percent of wastes compared to the usual cut-sew method of footwear manufacturing. With the Flyknit material, Nike can use single-piece knitted material that resembles a sock-like material that wraps around the feet for a snug fitting that adapts well to the contours of the feet.

  • Two colorways were introduced in the first quarter 2017 release: the yellow/black and a women’s exclusive white/black.
  • For Spring 2017, other colorways were released that include pink, olive, blue and red tones.
  • Thicker buckle straps in the updated version help give lateral and medial support and help keep the feet from moving too far forward.
