Nike’s nomenclature of its sneakers can get rather technical and futuristic, like ‘Flightposite’, brute and domineering, like Air Power Max, or downright simple, like Free Run. The Free was, in its earliest stages, a design concept fit for the ‘barefoot’ runner, and since its debut in 2004, the designers of Nike Free have done their best to give the shoe the lightest, second-skin-like construction to give the runner an experience ‘Free’ of superfluous materials. The Nike Free Run and Free Run 3.0, the most recent inclusions to the Nike iD menu of options, not only gives the runner the zeroed-in engineering, but a personalized design; you can choose between the 3.0 and 5.0 Free outsole and 3.0 and 5.0 Free upper – the 3.0 owning a seamless construction lighter package while the 5.0 offering the Dynamic Fit System. Four total combinations give you the freedom to choose what you please, so head to Nike iD now to design your own pair after checking out some of the design ideas below.
