Zoom cushioning > lunar base any day. Way more responsive and durable.
The unfortunate thing is that the 4, 5, and 6 had were legendary performers but each had a flaw that kept them from being perfect:
-4 - Forefoot lunar bottomed out after heavy play otherwise had the best herringbone traction.
-5 - Average traction otherwise perfect glove like fit and best heel cap lock down, good zoom cushioning.
-6 - Slightly better traction than the 5 but not as good as the 4, heelcup and fit not as solid and reliable as the 5, otherwise IMO best cushioning setup and best aesthetics for the signature 'mamba' shoe.
I think if they combined the 4, 5 and 6 into a single shoe, the traction of the 4, the glove like fit of the 5, and the aesthetic and cushioning of the 6, it would have been the all time GOAT kobe shoe and bball performance shoe.
I miss kobe.
