How they fit and how comfortable they are are the most important things. If you're going to be wearing these boots for hours at a time, you don't want to end up in pain after your first day on the trails. Remember, if you're wearing hiking socks, you probably want to move up half a size just to make sure you have enough room for you toes. You don't need a crazy expensive pair or anything like that, but don't buy the cheapest thing you can find. Decent hiking boots are a really important investment if you're camping regularly.
