Good technical shoes are a deal-breaker when it comes to hiking, trekking and hillwalking. Proper walking shoes or hiking boots prevent blistering and foot pain. These problems can show up unexpectedly on hiking and climbing tours. If a walking boot doesn't fit, it's sure to cause pain and frustration. Hiking and mountaineering are more about savoring the outdoor experience and the world of the mountains. It beats trudging around in painful hiking shoes on an agonizing climb to the summit. Proper trekking boots and walking shoes make it much easier to reel in kilometers and climbing altitude.
