First off, as the seller states, these shoes fit one size smaller.... almost exactly. So if you are a 9 1/2, order an 8 1/2. Secondly, expect to put these shoes outside for a month to finish off-gassing. As soon as I opened the box, I was almost knocked over by the toxic fumes!! The shoes are some sort of synthetic nuclear waste, mixed with gorilla glue and dog farts. I haven't been able to wear these in public yet for fear that someone might thing I live in a Harbor Freight. Yeah, it smells like HF, where all the cheap rubber and plastic, imported from a certain country, gets sold. So if you like smelling like a HF tool shop, buys these boots and wear them immediately.
