Just like with anything leather that you wear, they just seem to get more comfortable with age. I have a raggedy pair of leather shoes but I still love wearing them just because they’re the most comfortable pair in my shoe rack. Now, as for leather sporting equipment, you’d notice that they do get better after they get broken in. Here’s how to break in a leather baseball glove.
Use it. There’s nothing better to break in a glove by using it as often as you can in the shortest time possible. Play catch with it. Make sure the glove fits comfortably even if it hasn’t been fully broken in yet.
