Their upper features a new, seamless Airmesh jacquard fabric with a sideways XX blade design commemorating the anniversary. In addition, they are further reinforced in the medial area, with a piece of PU filled with XX blades that provides greater internal support. The outsole/midsole is the same as the previous version, with a Wave platform for smooth running without over-pronation. They also stand out for using sustainable materials, such as the wave platform made of Elastollan, a TPU made from plant biomass.Features: New, more breathable, seamless Airmesh jacquard fabric with XX blade design on the side to commemorate the anniversary More reinforcement in the medial area, with a PU piece filled with XX blades, also in PU, providing greater internal (medial) support Same outsole/midsole as previous version Thick midsole for increased cushioning for greater comfort Wave platform with a minimum number of waves for smoother running, but reinforced to prevent over-pronation 100% vegan shoes
