I'm actually pretty happy with my Kobe's they're not heavy at all and lowtop, comparable to my running shoes .. the only problem is, and this is a deal breaker ... is that they're not flexible on the top so i dont get much dorsiflexion (?). if i can find a pair of shoes that have that as well i'll be super happy for a dunking shoe (and general basketball).
i have the kobe 9's and i don't think i can find a better shoe for dunking indoors than them. they're low to the ground and flat, so they're not like typical basketball shoes where theres too much cushion and it becomes cumbersome for jumping. also the traction on them is literally GOAT lol. i also had the nike zoom streak lt 2's which have really thin cushion. on court theres barely anything separating you from the ground. the traction on them inside wasn't too good though, but if they did have good traction i would've ordered more pairs. i used them outdoors instead and the traction is completely worn out now.
i really like shoes with thin cushion though. might be a placebo, but i feel like i jump higher in them. you really get to transfer that energy straight into the ground instead of having soft cushioning absorb it. also cool how you can pass for a shorter height without wearing shoes with really thick cushion. my height without shoes is in between 5'11 and 6 ft, so i can pass for 5'11 in my zoom streak lt's and be a sub 6 ft dunker lol. i'm like 6/6'1 in my kobe's though, and 6'2 in my kd 7's.
