I had the mens engineer boots, without the buckle.(
Red Wing Leather Boots - Engineer - 2991)
Never found them too comfortable, very stiff, but that could have been because I never wore them long enough to loosen them up.
Mine were steel toed and the the reinforced part was not big enough. the edge ot the reinforcement pressed against my pinky toe and that hurt when walking so I never got around to using them properly.
They were very very good quality, extremely strong. colleagues that did wear them often said they were tough as nails!
The boot you're looking at looks more comfortable, and I'm sure they will last you a long time.
Do they have steel toes?
