Think about where you're going to be hiking and when. No single hiking shoe can handle every condition in every season, but if you're heading out in spring when trails are bound to be muddy or the area where you regularly hike has a lot of water crossings, waterproof hikers are the way to go. Most models employ a waterproof inner liner made of Gore-Tex or similar breathable material that wicks moisture away from sweaty feet keep them dry while creating a barrier to prevent water from outside seeping in. These materials are very expensive and extra labor is required to build them into boots, so costs for waterproof hiking shoes will be higher. The added cost is more than worth it, however, when it comes to keeping our feet warm, dry and comfortable.
