After 1 year of use (normal daily use) soles, in the heel, are pierced, and I now pump water from the floor ... my feet are not dry :-( I had invested in these shoes caterpillar (~ 120 anyway) thinking that this proposed resistant footwear brand that would last at least 2 years. In appearance (and see customers comments on Caterpillar shoes on this site) I thought too that the sole was indeed resistant; we realize that this is not the case when it is a little worn and shows its internal structure. Shoes that are not made to last. I am very disappointed with these shoes and caterpillar fact. Sincerely. PS: I made the same comment Caterpillar Jolt man Laced shoes, since they are the same products, at least the same soles ...
