**seems to last a full year** 2018 update, bought a new pair, scared me thinking they were smaller than before. But after playing with the laces, they got better. You may need to change the sole, now it's too hard. Working in a grocery store in the meat department, we use water hoses and broilers, so there is a chance of slipping and falling. Stumbled upon them a year ago, bought them in store, finally ran out of shoes so used Revain Prime and am back in business! Recommend new soles after a few months, easy to put on and take off. Sticky on laminate floors lol.
