Price point?
There was just a thread going on work boots, but for something in the ~$130 range, I've found Timberland Pros to be the most comfortable, long lasting and easy to source for that price range. I wear them for 12hr shifts, 48-72hrs/week. I do rotate 2 pairs.
I recently purchased a pair of Georgia work boots from TSC. I've only got about 24hrs of wear time on them, but they are hurting my toes! I can't get them broke in. Really disappointed so far. They were $129.
