Remember that a glove is going to be part of your physical makeup. In other words it has to balance you off and still fit the bill for a glove.
Some pitchers prefer a light glove that has little or now weight to it. Others prefer a glove that has weight to it. Either way, you can compliment your pitching style with a glove that “works with you,” not just something that looks good and a glove that everyone else uses.
Equipment is not an appointment that makes you any better than your training and desire to perfect your craft. Some pitchers use a different glove either during a game or for mounds that have a particular feel to them. Again, remember that a glove is an extension of your own body and how you balance yourself while working. And by the way, Zita’s suggestion is a good one, if you can afford it. In that regard, tag sales, rummage sales and garage sales can be a really good place(s) to get a good glove cheap.
