MY DD also has the finger holes too big. She tried the foam and didn't like it but I might try to look into what bog said. My DD has used the rubber bands and found them too uncomfortable. what she did all last season was tape her fingers. She uses the regular athletic tape and puts tape around the two fingers in the spot where the grips fit on her fingers. She wraps the tape around two or three times. This solved her problem. She still has to get the coach to do it for her. When she tries on her own she can't quite get it right. In addition to the holes feeling to big and uncomfortable it can be dangerous. Anytime my DD doesn't use the tape her fingers slip out of the holes. Often this has happened while doing things on bars. She has peeled a few times after her fingers slipped out.
