FLEX YOUR FEET. FREE YOUR TRAINING.
The Nike Free Trainer 3.0 Men's Training Shoe blends a supportive, dynamic-fitting upper with ultimate flexibility for a barefoot-like training experience.
The laser-cut upper features an extremely flexible yet durable material called Kirum. It delivers a second-skin-like fit that moves with each stride. Larger openings are located where more flexibility is needed, while smaller openings offer greater support during intense workouts.
The Nike Free outsole features deep flex grooves that extend from heel to toe and medial to lateral. Its Diamond Flex design enhances flexibility and multidirectional traction.
The low-to-the-ground design allows for maximum control. The sidewall wraps up the foot to cradle the heel and the midfoot, helping to keep it stable during side-to-side and diagonal movements.
Solid rubber pods at the heel and perimeter of the forefoot feature an aggressive delta-node pattern, providing traction and durability on multiple surfaces.
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. In 2002, they examined a group of men and women with pressure measuring insoles taped to their feet, using high-speed cameras to capture images of each foot in motion.
The team spent eight years studying the biomechanics of shoeless running. 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.
- Partial mesh inner sleeve for breathability and a snug fit that allows for easy on and off
- Dynamic Fit technology wraps the midfoot for a glove-like feel
- Straps anchored under the foot that connect to the laces allow for a customized fit
- Phylon midsole for lightweight cushioning
DiamondFLXNike DiamondFLX technology is designed to enhance multi-directional flexibility while providing a lightweight, low-profile fit. Strategically placed, diamond-shaped flex grooves offer the ideal amount of flexibility for training and enable the foot to move naturally in all directions, allowing for better balance, power and control.
Developed in the Nike Sports Research Lab, Nike DiamondFLX technology strengthens the foot while providing the support and stability athletes need for lateral training moves. This process helps to strengthen your body and make workouts more efficient.
