It’s hard to believe it’s been almost ten years since the first Nike Free hit the market. The shoe that brought the concept of barefoot running to the mainstream has remained a best seller for the swoosh, equally accepted by athletes and fashionistas alike.

Originally engineered by Tobie Hatfield and Eric Avar, the Free was first inspired by Stanford athletes that were training barefoot on the university’s golf course. Taking this study back to the Nike campus, in 2002 a group of men and women examined wearing pressure-measuring insoles taped to their feet and captured their data with high speed cameras to study the foot in motion. The result of an eight year extensive study yielded the understanding of a “natural” landing stride, demanding a new running shoe from the brand with minimal heel to toe offset, unconventional shape, and a super Phylon flexible outsole.

Perhaps considered a redemption shoe for many runners of past generations, the Nike Free is a landmark shoe for the brand that sustained many running myths over the past few decades including a raised heel or excessive cushioning and overlays. The original Free from 2004 transitioned from the brand’s approach to barefoot running to eventually accommodate training to become everyone’s favorite coffee shop runner today, here is The Complete Performance History of the Nike Free.

No. 1 – The Original Free

Sneaker: Nike Free 5.0 V1
Year: 2004

Released with numbering system from 0 (barefoot) to 10 (“normal” running shoe) from Free 3.0 to Free 7.0, there was talk of Nike wanting to do a scale of 0 – 12, but years later we've only seen a 3.0, 4.0. 5.0, and 7.0. (The reason for a ".0" continues to stump wearers as there isn't a ".5" sole, but then again the Nike Free has never stuck to the a simple titling or numeral system like most brands. ) This original Free featured a skeleton print on the insole for a literal interpretation of a “barefoot” ride, an upper that leaves room for improvement for breathability, and a traditional lacing system.

This cartoon straight from the "Nike Kitchen" sums up Tobie Hatfield's journey to the making of the original free:


No. 2 – No More Wimpy Feet

Sneaker: Nike Free 5.0 V2

No. 3 - The Mesh Era Begins

Sneaker: Free 5.0 V3
Year: 2007

No. 4 - The 3.0 Ditches the Overlay

Sneaker: Nike Free 3.0
Year: 2008

Containing a sturdy BRS 1000 outsole for extra durability and what looks now like a completely archaic upper, the mesh upper was a material upgrade from the previous version which featured heavier fabric overlays. The two panel mesh upper created a snug, compression fit, while the EVA midsole and strengthening BRS1000 carbon continued to supply durability. Weighing in at 5.6 ounces, the 3.0 was a super lightweight runner.

No. 5 – The Free Turns 4

Sneaker: Nike Free 5.0 V4
Year: 2009

The Nike Free hit the fourth year of production with the V4, at a time where barefoot running had hit its peak with the publication of Chris MacDonald’s book and countless articles on the subject. Following Nike’s system of 1.0 being a barefoot shoe and 10.0 being a traditional runner, the 5.0 was advertised as the perfect transitional shoe. The all-mesh upper featured minimal supportive bands, leaving room for improvement in future models.

No. 10 – Free Run+

Sneaker: Nike Free Run+
Year: 2010
