Using the existing bottom (midsole + outsole) from the previous Sonic, my task was to refresh the upper with breathability as the main focus. With the help of great material partners, the upper translated to a beautiful engineered mesh that has added depth while maintaining airflow.
FEATURES
- Lightweight engineered mesh upper for ultimate breathability
- Tongue is attached to the footbed by stretchable support wings to maintain a snug fit throughout the foot
- One-piece heel construction with external TPU heel counter for additional support & structure
