We have the Nike Free Run available in sizes for infants, toddler and youth. The breathable mesh upper and a multi-layer construction provide for a lightweight, second-skin-like fit. The sculpted Phylite midsole/outsole provides lightweight support and cushioning. The deep Nike Free sipes enhance flexibility for a barefoot-like ride.
