PHANTOM FREE

Phantom Free is a sandal with Nike Free sole technology that lets your foot move the way it wants to. The ergonomic shape mimics the natural movement of the foot for maximum comfort all day long.

NIKE FREE

Team Nike Free has been studying the biomechanics of runners' feet in motion for eight years. The new outsole features hexagonal grooves, creating six multi-directional motions that allow the foot to move more naturally than ever before. Secondary hexagonal and horizontal cuts cross flex grooves for even more flexibility.

Additional options:

Upper: 94.71% synthetic leather, 5.29% textile

Bottom: 100% rubber

Inserts of rubber of different densities are spaced across the entire surface of the sole and intelligently distributed at wear points for strength and durability of the product.
