Free 4.0 Flyknit 'Grey Volt'
Details
The Nike Free 4.0 Flyknit is a high-performance running shoe redesigned for competitive racing. This 'Grey Volt' iteration updates classic design lines in woven textile with dual-tone fibers, printed Swooshes and strategic perforation for breathability. Flywire cables connect to the laces for an adaptive fit while the rounded heel prevents slippage. The Phylon midsole and rubber outsole are maintained for response and flex.
