The last pair lasted me 3 yrs. Chemical/water abuse,standing for 12 hr days. Kneeling caused front toe piece to separate early,but didn't progress,thank God. Nice and light . Very comfortable. I've always have gone with the most cushion I could get. These are better , but the snug fit gave my feet total relief due to the way they are made to conform to the foot. No need to upgrade with squishy cushion soles. Fit is better!
