The Propulsion midsole is made of thermoshaped EVA for maximum lightness.
A central TPU element located between the forefoot sole and the heel gives extra stability to the structure in order to offer torsional rigidity.
The sole protection is offered by a second element in TPU, positioned between the EVA midsole and the rubber outsole on the forefoot area; what we term “visual technology.”
The main features of the rubber outsole are the innovative and bi-directional lug system: Aso Propel for accelerated forward movement, and Aso Brake for quick and responsive stopping.
The TPS sole improves comfort, stability and has a very distinctive look.
