Went half size up on these and they're still pretty snug. See how they break in. Reminds me a little of the Kobe 4 on foot which is a good thing.
Edit: they break in very nicely.
Those 31s were amazing except for traction which as you said is the one thing a hoops sneaker absolutely needs. Such a shame.
*same could be said of the Kobe 11 elites.
