The Nike Free Trainer 3.0 “Anderson Silva” 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.
