they look a lot like the lamelo model which looks a lot like the brand black metal joint.

btw on that note i have been hooping in some brandblack j crossover 2.5. GREAT shoe. initially i passed it over because it seemed a lot like the 2.0, which is a great casual shoe but just above average for bball. these have way tackier outsoles, a little more rubber in the midsole and much better containment in the upper. great shoe, i'd say top 20-25 that i have ever played in (and i've had em all since about 1995 plus a lot of older models I tried as well).
