I used to be an iron worker and had every boot know to man....Red-Wing, Wolverine, Danner, Thisted-X, Doc's, Wal-Mart specials, The best most comforable longest lasting and lighest boot I ever wore was a boot called Worx, they were made by Red-Wing and only came a little above your ankle but they lasted about 10 months and were only $80. Its worth a try. Here's a link to something very similar to what I have,
