I have only had for about 2 months and changed direction. Description from website below. THE ROGER Pro 2 Women`s Tennis Shoe by On is the second tennis shoe from On and Roger Federer. An abrasion-resistant mesh upper and perforated tongue give THE ROGER Pro 2 unmatched airflow in a lightweight package. So when the game heats up, you can move like lightning. On created a shoe that features some of the brands` signature technology, but with some new additions to be sure it holds up to rigorous lateral movement on the tennis court. To maintain stability, THE ROGER Pro is built with a solid midsole made from high-density, high-performance foam. The unit extends on the lateral side of the shoe, increasing the footbed size to add stability. A midfoot cage keeps the foot locked in during intense play, and a curved edge along the outsole helps deliver a smooth weight transfer into every ball. A 100% carbon fiber Speedboard™ was used in the shoes. The board absorbs impact during landing, and it returns energy for ideal balance on the next step. THE ROGER Pro 2 has improved stability, agility, and durability over the previous version. The shoe is worn on tour by world number 1 Iga Swiatek.
