He works with concrete and puts his workboots through the mill! He says these are the best boots I ever got him. He asked me to get him the same exact pair a week later so he can wear the other pair as "dressy" until the other ones are too beat to wear. He says Caterpillars are the best boots....He said "no" when I offered him Timberlands because he says they are good but more for hiking. He said he needs a tough boot and that's the Caterpillar.
