No Leaking! First goggles that haven't leaked in the dozen or more I have tried in the last 6 months. I have tried over a dozen different goggles in different price ranges and sizes with no success until these. I was very skeptical of these working. When I first tried them, there was a tiny bit of leakage around the right eye (a chronic spot for leaking for me). But all I had to do was empty the little that had gotten in and reset the goggle. Then they lasted through my entire swim of 1 hour and 15 minutes. So happy I took the chance. And after a couple of swims, they keep the water out from the very beginning.
