The aim of this study is to analyze foot pressure distribution of trail walking shoes while walking. Hiking, a recreational activity which is able to exercise whole body in the nature without any cost, has compositive effects which can reduce stress, strengthen muscles of entire body and improve cardiopulmonary function . The Topography is hard near the surface and has rough characteristic because of rocks. These condition can lead to injuries to feet in hiking and aggravating fatigability of foot when people hike for a long time ,so hiking boots which are specially functioned are encouraged because walking on the rough surface has latent dangerousness of injury . Trail walking shoes generally provide more stability and support than regular walking shoes. Trail walking shoes are for natural trails. In rocky, rooted, dusty and muddy trails, a trail walking shoe gives added traction and support.
Result of Foot Pressure
Maximum Mean Pressure(kPa)
Contact area of functional shoes (Type A) increased in comparison to general shoes (Type C, Type D). At the same time, foot pressure decreased in comparison to general shoes (Type C, Type D). It is expected that Type A Functional shoes give more comfort and fit by increasing the contact area and decreasing peak pressure.
In the result of the analysis of plantar pressure, Type A reported higher than other shoes on the forefoot. At the maximum force, Type A is observed as the smallest maximum force in almost part. These results, which is similar to Park (2009)’s research , decreased the confining pressure which can lead the deformation of forefoot’s toe. In the maximum pressure result, the outcome is similar to maximum force, which the smallest is Type A < Type D < Type B < Type C. This can decline the impulse which occurs in heel strike section, as a result, this can decrease the fatigability of foot in long-time walking. In addition, similar to Oh and Lee (2009)’s research , it can lighten the impulse force delivered to the body, as being the important factor which can decrease the weight to the leg joint. As examining the result of the average pressure, Type A < Type C < Type D < Type B is observed.
In this thesis, we analyzed the contact area of plantar pressure, maximum force, maximum pressure, average pressure. Through this result, we can know impact force alleviation for foot and physical fatigue, too.
When considering the pressure change of the foot, Type A’s contact area of foot is wider than the others. So, its wearing feeling will be better than the others. In case of maximum pressure, it is lower than the others and mid foot, hind foot’s result is similar. So, we expect ‘shockproof and to disperse pressure’ will be good. Also, with foot and shoe contact area’s increase, there may be amaximum force and maximum pressure decrease. So, it can decrease the foot’s and pelvic limb’s fatigue.
We offer the data of the dispersing pressure functionality of walking hiking shoes, so it can be of help to a product’s functionality improvement.
