Need some recommendations for a pull on work boot

Back story, my son is an industrial design major in college, and this semester he's got a forging and welding class. This is WAY outside of his normal routine, so he clearly has no work boots...and this isn't my lane either. Asked my brother in law who's a welder what he'd recommend, since the guy running he class told them to get "fire resistant footwear" and he said any full leather work boot with no laces. He said he either gets Ariat or Justin.

So I started looking through them all and sort of had no clue. I'm assuming it's worth it to get a steel toe version, but other than that I have no idea which styles guys find the most comfortable and easiest to wear. I'd call him back and ask him, but he's gonna say something like, "I don't know man...whatever they had." You guys tend to be pretty particular about things so I figured you'd have tons of opinions. I don't want to get the kid something that's going to be super uncomfortable, because he'd either wear them with his feet bleeding so as not to complain, or stop wearing them altogether and then make it an emergency to try and get a replacement.

Thanks.
