PureBoost 'Grey'

Launched in 2013, Boost technology offers runners an unprecedented energy-returning response. The adaptive nature of the Pure Boost mixes performance and comfort with a molded heel counter for achilles movement. A considered tongue design allows for easy instep and lower foot pressure, and the StretchWeb outsole helps with traction and stride. Made for the city runner, the lightweight Pure Boost is designed to combat slippery and uneven conditions.
