I love my new shoes, they are SO comfortable and perform well on the court.
Design has changed for the worse
I have a pair of Challenger 12 shoes, which are extremely comfortable for unlimited play. The newer 13 model has design changes: narrower in the toe box, less breathable mesh, and the footbed applies pressure to the side of my foot. As a result, I can only wear these shoes for at most an hour of play before they are too uncomfortable to wear. I would love to buy more Challenger 12s but cannot find any in Size 8.
