If there is one question you should ask yourself before choosing your footwear, it's “what type of hiking am I going to do?”.
That is to say, on what type of terrain? For how long? And how heavy is your backpack?

If you're walking on lowlands you won't have the same needs as for mountain walking.
Each type of terrain has its own particular features.
