We recently laid tiles in the house and my husband had back pain. Bought these for him and he loves them! These tennis shoes are very light, have great heel and arch support for his flat feet, and are very cool due to the many air holes in the fabric. Most importantly, his back no longer hurts from standing on our tile floor for a long time! He usually wears a size 10.5 but that size was sold out so I ordered 11 and they fit perfectly!
