The Official Size fit most hands, and they are extremely effective when worn correctly - even for smaller hands. Have you tried just putting one finger through the slit? Try just your pinkie or just your pointer finger. For some people, if you use both slits, you may have a gap between your palm and the grip. Try this and see if it makes a difference! But of course we will be happy to exchange them for you if you feel the fit is not right. Get in touch with us here!
