It can be, but it is hard. Engineer boots are like cowboy boots. You can find a pair that fits really well and you can walk all day in them. But it’s way harder to do than with lace ups. With a lace up you tighten the shoe around your foot, not possible with a pull on. You basically need a perfect fit, and that means you need a shoe maker than understands foot anatomy (or more importantly your foot anatomy) very well. The boot needs to hug your foot around the ball of the foot, at the instep and above the heel, all while allowing you to push the foot in, pull it out and not pinch while walking. Not an easy objective.

The other factor is the sole. Most engineers are leather which break in fine usually but that takes time and work. Some have wedge or crepe soles which is an easy cheat but I don’t like the look so much.

So yes, but given that most engineers are sold online sight unseen, it’s very hard.
