Omni Court Black tennis shoes with a lightweight and grippy outsole. - Brand: asics - Color: Black - Style: Tennis shoes - Sole features: Grippy outsole Thank you for viewing. Purchased last fall, used 5-6 times on an indoor omni court for 90 minutes each time. I think the soles show almost no signs of wear, but this is just my personal opinion. The soles have been lightly rinsed with water.
