So I've been wearing these a lot recently; they're so comfortable compared 3s, 4s, 5s, 6s and even AM95s that have the enormous airbag (though the PSI is way to high). What is it about the 7s that make them so much more cushy than the 6s? You can tell that the midsole of the 7s is inspired by the same shape as the 6s, but they're so much softer. Obviously the material is different as the midsoles of the 6s are hard and don't crease, while the 7s crease. I don't care about the creasing...just obviously more flex going on there.
Ironically, I lost interest in the '90 after the 6s b/c I love visible air. I had the Bordeaux in '92, but didn't like them b/c of no visible air, and my preference for all black shoes, then the Aqua 8s in '93, and never liked them b/c no visible air, and how clunky they were. Anyway, really come to appreciate these now b/c of the nostalgia of those times, and the comfort.
