"It seems like every time I start swimming laps again, my ears go into panic mode and completely forget how to deal with water. These Nike Swim Ear Plugs ($13) are simple, comfortable, and effective. They keep water from getting clogged in my ears and can lessen the chance of getting earaches. And I love how they come with a small, waterproof carrying case, because I am exactly the type to lose them in my gym bag." — Maggie Ryan, assistant editor, Fitness
