If you’re looking for ultralight size 12 trainers then look no further than the Nike Free Trainer V7 Men's Training Shoe. It delivers the stability and versatility you need for high-intensity workouts—and adds the incredible flexibility of a Nike Free sole.
Flexible movement, stable stance
With each step, the updated Nike Free sole expands and contracts in all directions, following the natural motion of your foot. A 3D-printing-enhanced upper provides targeted areas of durability, breathability and stability right where you need them. A half-sleeve design with Flywire cables and stretch bands provides a locked-in fit during intense workouts—while still providing easy on and off.
The origins of Nike Free
After learning that Stanford athletes had been training barefoot, 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 four 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.
