Nike Flex Trainer 4 blends a supportive, dynamic fitting upper with multi-directional flexibility for a barefoot-like training experience with phenomenal stability.
Dynamic Fit technology features straps that wrap up from the midsole and integrate with the laces for lightweight support that moves with the foot.

Synthetic overlays on the toe and heel enhance durability in these high-wear areas.
Traditional tongue made of sandwich mesh helps reduce lace pressure on top of the foot.
Injected unit sole material in the midsole provides cushioning that is durable enough to double as the outsole, dramatically reducing the overall weight of the shoe.
Outrigger provides lateral stability and support.
Minimal rubber pods placed only in high-wear areas provide lightweight durability and traction without limiting flexibility.
Deep flex grooves allow the foot to move in a natural motion.
Traction pattern allows for multi-directional movement.
