After having walked several miles without bearing blisters or calluses in my feet, I have become a big enthusiast of walking boots. Their rough and tough look tells you a lot about their function but that is not enough. The more you discover about them when you wear them while going out one day for a long walk.
Often walking on rough terrains, hilly areas and stone paths, you develop pain in your feet and the sole of your feet burns. But that happens when the sole of your shoes is not giving you enough support to keep safe from the pointy and bumpy obstacles of your path. The toes also become tired and ach terribly when they do not find enough room to stay snug in. The narrow front part of the shoes is not often made comfortably roomy but this is not the case with walking boots. They have extra thick sole and no matter how pointy or hard an object is that you trod on, your feet do not get directly affected from it.
Assortment of colors and designs are all decent and matching with the rough and tough paths where you might walk with them. The choices in pure leather upper are more robust but they are a bit stiffer than the man-made material. The benefit of leather is that it can be polished and rubbed well to shine and look novel even when it becomes old. Choosing light weight man-made material has different advantages that you would not prefer leather on them. So, selection is yours!
