Many new customers ask about the design of Nicks boots, especially the four layer, strong arch and heavy heel. Nicks boots are designed to closely simulate the natural form of the foot and to distribute body weight evenly among the heel, arch, and ball of the foot. In a vast majority of customers, this feature helps minimize foot and leg fatigue as well as lower back pain attributable to inadequate foot support. Your boots must be more than just foot covers. They must be strong enough to support your whole body, especially during strenuous work.
