2XU Tri Suit - Leg Gripper Help

I've got a 2XU tri suit similar to this one, but it's a couple years old:



The leg grippers have pretty much given out, and these things ride up my legs while I bike and run.  The rubber on the legs is VERY thin (for speed reasons, I'm guessing) and won't take to sewing/stitching.

Is there any glue or anything you can think of so that I can get the legs grippers a little tighter (e.g., fold over the rubber at the bottom of the leg and glue it) so they don't ride up on me?

Thanks in advance.
