I have worn these shoes for 3 years both as a FP softball umpire and football official. Other than wet grass, they have great traction. (Only slipped once but did not fall). These shoes are extremely comfortable. I would have loved to try them as a basketball official. The Spotbilt shoes are not comfortable on wide feet.
