I have a pair of the same ones I bought 25 years ago they are almost through the soles on the balls of each foot I wore them for 15 years as good shoes and then as socks for difficult tasks. I put them on at my mom's this morning to spray spray with bleach to kill the moss on the driveway. So far it's comfortable and hasn't torn anywhere. I call it great service and they're almost the most comfortable shoes I've ever had.
