Where do u choose size of shoe?

this might be a different seller and its only the size in the description, search this show again and make sure its not one size and gives options.

Are these shoes puncture resistant?

Yes, it is like the normal reebok shoes.

What are they? One description states EH and another states ESD. They cannot be both.

This was also my question. There are several mentions of SD10 and dual resistors, and apparently they pass esd testing, which means they cannot be EH. Although several sellers both within and outside of Amazon do say they are EH, there is nothing official from the manufacturer which claims EH. They also mention ASTM F2413 which is fairly generic. F2413-18 is the specific code dealing with Electrical Hazard. There are many “creative marketers” in Amazon who advertise claims they don’t understand which makes it difficult to find what you’re looking for. Even a Google search for shoes with specific attributes brings up several ads for these that do claim these are EH. Reebok, on the other hand does not say they are EH. This particular ad doesn’t even say for sure that this is the 4041 model, which some people say has alloy toe and some people say has composite toe. It’s as frustrating as trying to buy specific tires on here.
