Nike Men's Flyknit Trainer Running Shoes - Lightweight Breathable Sneakers for Jogging, Gym Workouts & Casual Wear

Where resilience and versatility meet: the Nike Free Trainer 3.0 is one of Nike's many innovations to further develop a sports shoe technology that is modelled on the light, natural feel of barefoot running. The Free 3.0 combines a lightweight, supportive, breathable upper with a highly flexible "natural" outsole. • Mesh upper for consistent breathability with maximum durability • Flywire fibres surround the arch for a firm, yet unobtrusive comfort • Phylon midsole for durable, reliable cushioning

Soft and comfortable Max Air cushioning provides just the right level of support.

The outsole with waffle texture and flex grooves provides traction and resistance.
