Without looking in your golf bag, identify the manufacturer of your grips and what style they are. Most likely, you can't answer those questions; most golfers can't, either. What you don't realize is that great strides have been made in golf grip technology, and you may be overlooking a way to easily improve your game. Great strides being made with grips that make your clubs easier on your hands while offering more feel with your shots.
Look for grips that are easier on your hands, particularly if you have issues with your elbows, arms and hands. Some grips now made by Eaton/Golf Pride and Percise are made of extra-soft thermoplastic that many say are a true pleasure to use. Great strides have been made with soft grips to keep them from twisting at impact, a complaint heard by golfers who purchased them in the past.
Check out several companies that make golf grips that reduce the effect of moisture and stay drier, if you have a problem with excess perspiration or you play in an area that gets a lot of rain. There are other companies that make grips that contain cord to counteract wetness problems and they are easier on your hands than cord grips used to be.
Look for grips that have plain grooves if you find patterned or dimpled grips distracting. In fact, some manufacturers make clear grips that you can see through to the shaft, a favorite of Charles Howell III and other playing pros.
Select different grips based on the way you use a particular club. For example, there are grips with no tapering for wedges that allow you to more easily grip down on the shaft for shorter distances. And, of course, with so many people using a long putter, there are grips that are extra-long to accommodate them.
Adapt your grips to fit your circumstances. For instance, if you have large hands, you probably would feel more comfortable with larger grips. Also, if you have a tendency to hook the golf ball, consider building up your grip with tape in the area where you place your right hand that will reduce the amount that you pronate your wrists.
