It depends on what sort of style you are really. ironically i own that pair of vans. I like the DC shoes as well. It's really up to you depending on which is the price and style for you. just my 2 cents on the subject.
I personally like the DCs more; I myself have a black and purple pair ^^ But as mikes41720 said, it depends on your style and how much you are willing to pay.
I've owned countless pairs of DC's. extremely comfortable and durable, get them. but it depends on the pricing, because DC's can be in excess of $20 more than Vans.
Whats your dressing style like? If your more Casual.. go for the Vans. If your for skates.. go Etnies. Etnies pwn. Yeah I know theres no Etnies choice.. but Etnies would go nice with almost anything unless you wear those tight ass jeans like those emo people.
DC Shoes! Ive been wearing them since I started skating 5 years ago. Only other skate shoes ive wore other then them were Adio cus they were my friends. DC Iz Da Bezt!
Out of them 2? The DC ones look alot better. But I'd choose Adios or DVS over DC and Vans anyday. :-o
