If your swimming goggles keep leaking, despite you adjusting them to fit your nose, and around your head, it might be that they aren't the right pair for you. Despite these swimming goggles being the best on test, they might not be the best for your face shape or bone structure if they keep leaking.
It's also worth noting that if you're swimming quickly, diving into the pool, or doing tumble turns, your goggles might leak more than if you're just doing laps. If tightening and adjusting them doesn't solve your problem, it's worth shopping around for a different pair.
