Whatever you take on Nike being in the skate market, it is nice that they actually took the time to make skateboarding shoes that work well. Like everything with skateboarding, you should do what you want, and express yourself. If you like the look and feel of Nike Dunk SB's, then go for them. People like the strong response and board feel that Nike Dunk SB's give, and some of the colors are sick. It's also nice to have a pair of skate shoes that can double for other sports - most large puffy skate shoes don't work that well for other sports.
