I love these shoes! I had 3 pairs and am about to buy a 4th pair. I play them pickleball for about 6-10 hours a week on a variety of surfaces (regular courts and impromptu outdoors in our area). They last me about 6 months before the tread on the soles wears down enough that they start to slip during aggressive lateral movements. Lightweight, breathable and great support. If you play several times a week, you should change your shoes every 6 months.
