 I had a fantastic summertime vacation with my granddaughter, Payson. Eight years old, and when you take an eight-year-old on summertime vacation, you know you're going to do a lot of walking. But my G-Defy shoes really perform, and not just for me, but for Tina, too. Remember, when I brought home my G-Defy shoes, Tina immediately tried them on, even though they're the wrong size, and said, get me a pair of these. They're fantastic. And it turns out, after a lot of road miles, they are fantastic. G-Defy shoes have VersaSock technology.
