If you mean what's the deal with two gates instead of one... it's biggest advantage is probably that they hold the strap out wide making easier to slip your foot in. Especially with big feet or when I wear my Adidas (that's all I wear except only when I ride the track bike). I have an old pair of Gravis Tarmac mids that are perfect riding sneakers and are frigg'n awesome all around, but they are beat. DAMIT, I have to find another pair. i don't like how they changed them up.
