poor quality

I finally break down and spend big money on some high quality boots.   So I look around and try Danners 340.00 dollars I spent on these boots. The first pair lasted five months. The steel plate in the sole started moving took them back got a new pair now not even a month later the strings are getting loose on the front of both boots and the leather is seporating away from the steel toe.tell me some thing to convince me to keep buying the. I do tires for a living. At the end of the day my feet dont hurt.thats the best thing about them
