This is a running shoe but with a good lateral stability, so I use it for Zumba and it works great. Im a 7 1/2 in New balance, in Nike and Reebok and Salomon ( speedcross 3 and x-mission) but for this one I should have ordered the 7.
The quality is above my Nike, Reebok and New balance, as well as the comfort (considering that I own 30 or 40 pairs Im a god benchmark ). The quick lace system is definitely a plus. But the pocket for the lace for me is not practical at all, so I do like usual : tuck the end of the lace underneath the first row of lace. I admit they are on the pricey side (btw like my Nike) but I would buy again without a doubt... they loose one start because of the size issue.
