They have a piece of foam inside the glove that keeps you from making a good tight fist. On top of that it doesn't do your wrist much good either. A good tight fist protects your hands, if you have trouble closing you hand with these new gloves the delicate metacarpels in your hands can move around which is prone to injury.
If I could find an old glove in good shape I'd buy it on the spot. You can only put in so much work to break in these new gloves, but in the end it's better with the older gloves. You want a firm straight wrist, and solid tight fist.
