Im in construction so i am on my feet 8 to 12 hrs a day 6 days a week. By far these are the most comfortable boot that I have put on right out of the box. I've tried a lot of other brands out there and these have been easy to brake in and not kill the feet.. as for how long they last we will find out but so far there fantastic.. I will be getting another pair soon cause I feel they are well worth it
