Nike Flyknit Trainer History

The Flyknit, a technology used by the Flyknit Trainer, was first introduced in February of 2012. It was a revolutionary method of making shoes using one piece of fabric and where every stitch is micro-engineered to create a form-fitting, light, and seamless upper. This technology came about from four years of research as well as 40 years of applying knowledge gained from working with runners. The aim of the Flyknit was to reduce as much weight as possible by trimming away all unnecessary parts and produce a shoe that would give the feel of a sock but with much more support.

The Flyknit technology has since been applied to various Nike running, basketball, training, soccer, and lifestyle models but the first two silhouettes to use this technology were the Flyknit Trainer and the Flyknit Racer.

The Flyknit Trainer was released in that same year, 2012, right before the London Summer Olympics but wasn’t an instant success. It was more expensive than others and the sole wasn’t as durable as it should be for a running shoe. It only achieved fame after Michael Phelps climbed the podium six times to receive his medals wearing a bright-yellow pair of the shoe.

The Flyknit Trainer originally launched in a White/Black colorway along with nine other additional colors including “Volt.” In 2013, new colorways were again released but the original stopped circulation in that same year. In 2014, Nike debuted a women’s version of the now-classic shoe.

This 2017, to celebrate its 5th anniversary, Nike brought back the Trainers by dropping a White/Black OG along with three new colorways such as the Sunset Tint, Cirrus Blue, and Pale Grey in July.  A few more colors followed including Bright Citron and Night Purple.

Nike Flyknit Trainer Style

The Nike Flyknit Trainer is a versatile shoe that combines function and fashion. With its various colorways that range from subtle and low-key to bold, there’s something in it to suit every taste and preference.

The low top Flyknit Trainer looks best when paired with shorts, jeans, and chinos. It’s a good performance shoe but works best as leisure wear.

Fit & Sizing

The Nike Flyknit Trainer is offered in men’s sizes ranging from 7.5 to 13. This low top shoe may run a bit narrow for some. Many reviewers advise going up a half size higher.

Notable Features

The most notable feature of the Flyknit Trainer is its use of the Flyknit technology, which has recently made the transition from using manufactured polyester to recycled polyester as the yarn core of its shoes. The Flyknit technology now makes use of recycled PET bottles to produce new yarn and convert these into fabric.

Aside from the breathable Flyknit uppers, Flyknit Trainers also feature Flywire Cables and elasticated ankle surround for improved comfort and support. It also utilizes its signature rubber sole unit that has an excellent grip, along with a supportive midsole.

Additional Info

  • The Nike Flyknit Trainer weighs in at around 8.4 oz.
  • The Flywire cables provide good lockdown feel in a quite minimalist upper.
