One sure-fire way to tell whether a sneaker needs to be re-retroed is the eBay frenzy that results from a listing. And judging from these Tech Challenge IIs, it's high time Andre Agassi's 1990 classic hit shelves just one more time. These blue/orange size 11 retros from 2006 are drawing plenty of action — as are the same seller's Hot Lava pair. The remarkable thing, of course, is that you will be able to score both pairs for a fraction of what you'd pay for a pair of Air Yeezy IIs — which wouldn't even exist without them (check the midsole).
