Visable air cushioning, Padded heal collar and tongue, Arch Support, Cushion, lightweight, performance, breathable mesh upper, non-slip rubber out sole The story behind Air Tailwind series started as a road racing shoe, then Nike introduced the Plus-enabled version in 2009, the shoe held the capacity of tearing up tough terrain equally as well. A full-length polyurethane midsole embedded by Air pockets in both the heel and forefoot offered cushioning and stability on uneven surfaces, while the same BRS 1000 rubber outsole seen in the previous version stuck around to make sure runners stayed on their feet.
