Shop for Nike Free running shoes at Nike.com
You probably know by now that Nike Free shoes offer a barefoot-like feel, along with cushioning, support, traction and underfoot protection. You might even be wearing a pair right now. But did you know that not all Nike Frees are created equal?
The three different midsole/outsole types—3.0, 4.0 and 5.0—offer a range of flexibility and support. The higher the number, the higher the level of support. Nike Free shoes with a 3.0 outsole (the Nike Free 3.0 Running Shoe, for example) feature Nike’s most barefoot-like ride to date. It’s incredibly flexible and ideal for those who like to be as close to barefoot as possible while still wearing a shoe.
The 4.0 midsole/outsole (featured on the Nike Free 4.0 Running Shoe) is still very flexible but provides more support than the 3.0. The 5.0 midsole/outsole (featured on the Nike Free Run+) is the most supportive of the three, yet still offers a barefoot-like feel. The choice is yours.
