There are only two boots that will last in that industry, timberland pro and redwing. Both are very expensive, but worth it considering he will spend 10-14 hours a day wearing them. Tell him to put away $25/month for boots when he's working, generally guys in that and similar industries spend up to $100/month on their work clothes when you factor in good overalls, boots, glasses, gloves, jackets and winter overalls (if you live where it gets cold) and more if they buy their personal fall pro harness.
