Most comfortable work boots?

I've worn most brands.
Red wings and Chippewa (great boots) are hard as a rock and brutal if you have a foot problem. Timberland pro are slightly better.
Look more towards the higher end wolverine offerings.
Or the boots my company shoe store calls marshmallow boots, Rocky Duty Alpha force.
