I learned a long time ago from a footjoy representative that the average golfer is wearing too big of a glove. Whether you are using the square to square swing or any other golf swing, you need to have the right sized glove to perform your best. Oh and definitely use leather over synthetic. Golf is so much about feel. Using a glove that gives you better feel is so important. I use asher golf gloves – click this link to get a discount!
