The larger perforations are strategically placed in areas that need more flexibility while the smaller perforations are in areas that demand more support. The arch has been modified with transtarsal diagonal flex cuts for enhanced twisting, strengthening, and natural motion flexibilityIn the Nike Free continuum, the lower the number in a shoe’s name, the closer it comes to barefoot running (on the continuum, 10.0 represents conventional footwear while zero represents the bare foot). The Nike Free 3.0 shoe is the closest Nike has come to delivering a truly barefoot experience for optimal foot strengthening and flexibility.Ball-to-Heel offset = 4mm differential heel to forefoot drop: The lower the number, the closer to to ground you are and the more it stretches your Achilles tendon. This helps you run more naturally and barefoot-like.The Nike Free 3.0 v4 is ideal if you’re a runner who wants the strengthening benefits of barefoot training, but you don’t want to sacrifice the underfoot protection or multi-surface traction of footwear.

More cushioned than the Nike Free RN Motion Flyknit, the Nike Free RN Men's Running Shoe features a newly designed midsole pattern that expands, flexes and contracts with your foot with every step. Its lightweight, breathable mesh upper helps keep your feet cool and comfortable from start to finish.

SOFT CUSHIONING
Softer than previous iterations, the new midsole foam delivers exceptionally comfortable cushioning and lightweight durability for miles.

NIKE FREE ORIGINS
After learning that Stanford athletes had been training barefoot on the university's golf course, three of Nike's most innovative and creative employees set out to develop a shoe that felt natural and weightless, similar to bare feet. The team spent eight years studying the biomechanics of runners' feet in motion. The results yielded a profound understanding of the foot's natural landing angle, pressure and toe position, allowing Nike designers to build an unconventional and flexible running shoe from the inside out.
