  • The purpose of this research is to develop functional midsole that can restrain the heightening of plantar pressure in forefoot pressure so as to develop high-heeled shoes that can lessen foot ailments among women. The pumps shoes used for the research were of the same pumps type last. The variant was heel height, 3cm, 6cm, and 9cm, and the shoes were made in both normal midsole and functional midsole. The variant was applied to investigate the changes of foot pressure on forefoot and hindfoot according to heel height.'Heel Cup' was chosen for modification of functional midsolepumps type. to enlarge contact area in hindfoot, and 'Heel Posting Pad' was attached under sustentaculum tali to suppress the weight moving to forefoot pressure. If such functional parts are developed and used, it is possible to lessen the amount of Pmax or Impulse imposed by high-heeled pumps type on forefoot pressure. This can greatly lessen foot ailments, largely caused by high-heeled shoes, among women.

  • The history of foot-binding was once regarded as a unique practice accentuating the beauty of a woman and the culture of the costume, to be found nowhere except in China. This thesis makes it an aim to understand the culture of costume in China by analyzing the beauty of foot-binding, and its meanings associated with the historical background of the costume. The method of investigation was by both previous literature on the topic and case analysis. The shoes were analyzed by colors, patterns and decorations; selecting 70 pieces easily accessible in the Tianjin Huaxia Shoes Culture Museum. In terms of form, the general type was of the most frequent, followed by one with an elevated toe, mixed type, and one of the downward toe, sequentially. The color of foot-binding shoes were mostly vivid chromatic colors, while the achromatic ones like black and grey constituting significant portions. In view of the patterns, plants patterns were the most frequent, followed by the mixed patterns of mostly flowers with butterflies, bats, and birds desiring the prosperity of descendants. In view of the ornaments, embroidery was the most frequent, while the mixed shoes included tassels, sequins, applique, and shoes without ornaments were of distributions. The forms, colors, patterns and ornaments clearly associated with the wishes of artistic beauty, sexuality, and rise in women's social status may be in the hope of leading others to understand the costume culture embedded in the Chinese by providing important clues about them.

  • The purpose of this study is to find biomechanical parameters for optimal shoes production through an ergonomic usability assessment of five existing types of shoes preferred by B-BOY. Ten experts and ten non-experts participated in the experiment, and 12 infrared cameras (Qualis, Oqus), force plate (Kistler, 9286AA) and foot pressure plate (Zebris Gmbh, Zebris PDM-System) were used to obtain the data. The results of the study are as follows. First, P shoes with a friction coefficient of 0.38 and a free moment of 0.32 N/m/kg are desirable in terms of traction capability and safety. Second, on the cushion, it was found that the N shoes 2.51 N, sec/kg and non-expert, and 2.86 N and sec/kg were suitable. Third, it is deemed appropriate for C shoes with a forefoot average pressure of 10.11 KPa (right), 10.05 KPa (left), and V shoes with a rearfoot average pressure of 8.4 KPa (right) and 8.36 KPa (left). In conclusion, the combination of the structure and material of V shoes should be developed for traction and stability, N shoes for cushion, and walking balance for C and V shoes.

  • This paper presents is a study on the pressure distribution families low in response to ground conditions. Indoor shoes, outdoor shoes, working shoes, are four categories of shoes sports shoes, has been used in the present study, Concrete to target men in their 20s of 45people wearing the 260mm(Euro Code EU40), the experiments were carried out in the sand ground. Measurement of stress and pressure at the time of walking, Techstorm company Insole System the measured toe of the foot using, foot binding, was the metatarsal, the low pressure come from Fujoku four areas measured. Depending on the shoes and ground conditions findings, the results of this study represents the distribution of other stress and pressure, is expected to be useful in the development of a wearable shoe sand soil.

  • The purpose of this project was to determine biomechanical differences between Type A(Korean brand) and Type B(world top brand) badminton shoes and to make recommendations to improve the fit and function of Type A badminton shoes. Measurements of shoe shape and dimensions, foot movement within the shoe, cushioning of ground reaction forces, in-shoe pressure and outsole traction were performed. In addition, subjective feedback of the fit and function of the shoes was quantified for 17 recreational badminton players. Type A shoe had a much higher heel and shallower heel cup, so the heel was not secured well in the shoe and the ankle joint was higher off the ground. Foot slippage was up to 40% greater in Type A shoe than Type B shoe. Impact forces and peak pressures under the foot were generally higher with Type A shoe compared to Type B shoe. The flexion axis of Type A shoe occurred in the midfoot, not at the ball of the foot like Type B shoe, where you would want the shoe flexion to occur. In summary, there are several characteristics where A Type shoe and B Type differ. Therefore, a few recommendations are provided to help improve the fit and function of A Type shoe.

  • This paper is concerned with the numerical investigation of the landing impact characteristics of sport shoes to the landing mode. In most court sport activities, jumping and landing are fundamental motions, and the landing motion is largely composed of forefoot and rearfoot landing modes. Since the landing impact may, but frequently, lead to unexpected injuries of players, the investigation of its characteristics and the sport shoes design for reducing it are of a great importance. To investigate the landing impact characteristics to the landing mode, we construct a shoes-leg coupled model and carry out the numerical simulation by an explicit finite element method.

  • 본 연구는 전통적 하이힐과 수정보완된 하이힐 착용 시 간에 서있는 자세에서 족부압력과 정적균형을 비교하여 수정보완된 하이힐이 서 있는 자세에 미치는 영향을 알아보고자 하였다. 여대생 15명을 대상으로 하루 간격을 두고 동일한 대상에게 전통적 하이힐과 수정보완된 하이힐을 각각 착용하게 한 후 족부압력과 정적균형을 측정하여 비교 분석하였다. 그 결과, 수정보완된 하이힐의 족부압력은 전통적 하이힐보다 전족부는 유의하게 감소하고 후족부는 유의하게 증가하였다. 그리고 정적균형 능력은 전통적 하이힐보다 개선되었으나 유의하지 않았다. 따라서 수정보완된 하이힐이 전통적 하이힐보다 좀 더 정상적인 족부 압력을 가지게하고 그에 따라 균형능력에도 긍정적인 영향을 보일 것으로 생각된다.

  • The purpose of this study was to evaluate the effects of forefoot rocker shoes equipped with a metatarsal bar on lower extremity muscle activity and plantar pressure distribution. Ten healthy women in the age of twenties were participated in this study as the subjects. All subjects walked on a treadmill(Gait Trainer, BIODEX, USA) wearing normal shoes and metatarsal bar shoes, during which the plantar pressure distribution and muscle activity were measured. Using Pedar-X system(Novel Gmbh, Germany), the plantar pressure was measured for six regions of the foot: forefoot, midfoot, rearfoot, 1st metatarsal, 2-3th metatarsal, and 4-5th metatarsal, and for each sub-region, 4 features such as maximum force, contact area, peak pressure, and mean pressure were analyzed based on the plantar pressure. EMG(Electromyography) activity was measured by attaching surface electrodes to the rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius medial head, and magnitude of muscle contraction was analyzed in IEMG(Integrated EMG) value. The results show that the maximum force, contact area, peak pressure, and mean pressure in the midfoot all increased while maximum force, peak pressure, contact area, mean pressure in the 1st metatarsal and 2-3th metatarsal all decreased when wearing functional shoes. Also, muscle activities in the four muscles were all decreased when wearing the functional shoes. This paper suggests that forfoot rocker shoes equipped with a metatarsal bar can help disperse the high pressure and absorb the shock to the foot as well as give positive influence on gait pattern and postural stability by reducing muscle fatigue during walking.
