I've worn the NB 574 and must say that it is the most convenient date sneaker is I had. Since I found the Eclat 89 visually appealing, I ordered 2 pair of them. They run some pointed to (forward) as the 574. This one has a little more air, which I do not think so optimally. Overall, 574 sit better and also make use of the processing a slightly better impression. All in all, the Eclat 89 not a bad shoe, I would, however, bring me no other pair of them, as the NB 574 makes a better impression in every respect
