Etnies are an extremely comfortable shoe. When I was looking for a new pair of sneakers, I tried on everything! I tried on Vans, and DCs, but when I tried on the Etnies, they were the most comfortable shoe I'd worn in awhile. Although they were expensive, sixty dollars at Olympia Sports, they have definitly been worth it. They are all purpose, very stylish and mesh with most outfits. I myself own a pair of black Callicuts (I'm a punk) that go well, especially with a pair of dark bootcut jeans.
How are they comfortable? They're made of high quality materials. The sheepskin makes it very durable, and the foam on the inside makes it just squishy enough, but supportive at the same time. They're also quite breathable.
Also, they're durable. I've had mine since the beginning of October, and they're good as new! One word advice: because they're sheepskin, water proof them, and buy them a half size bigger than your normal size because the toe part is very low.
