Query: Great Fit, Highly Recommended

I have always had trouble with swimmers ear, and I just now got around to buying ear plugs. I used them in the pool today, and they worked perfectly. Soft, comfortable, but airtight fit that kept the water out -- I was finally comfortable swimming laps again. The only thing I noticed about them is that the pressure builds pretty high below depths of about 4 feet, because air in your ear canals has no where to escape.Overall, I love them.
