Back when DD was a catcher, I got her a new Vinci Fortus in the offseason to replace her light Mizuno that had left her with a thumb sprain. That glove was a beast -- she couldn't close it using two hands on the outside! I spent months pounding that thing: oiled it, lathered it with shaving cream, drove over it with my car, baked it, and finally took it for a steam at Dick's. The steam is what finally loosened it enough that she could close it, but of course it was heavy. But it was much easier for her to adjust to the weight of the glove than to try and catch a ball without squeezing it.
That glove got a ton of use, she caught more than 70 games that year with a #1 pitcher who threw in the low 50's. DD is a pitcher now, and three years later I'm still using that same glove to catch her. Maybe that says more about the quality of the Vinci, but the glove is still in pretty good shape.
That said, I've never steamed a regular fielding glove and never had a problem getting a new one ready in a couple of days.
