This research to reveal the foot types of old males consisted of two parts. First, a questionnaire was given for 180 old men in their 60s and above who live in Busan. Second, based on this survey on the reality of shoes wearing, direct and indirect measurement were held for 200 old gentlemen. The findings are as follows: 1. Survey Results of Shoes Wearing Reality In the investigation into the reality of shoes possession and wearing, most of old males favored active casual shoes with comfortable materials (40.8%). Hardened skin (23.6%) was the greatest in foot deformation and side effects resulting from shoes wearing, while the big toe (20.1%) was most uncomfortable. The greatest requirement for comfortable shoes was shoes making feet comfortable with a good sense of wear (41.0%), followed by shoes with the soft sole to absorb shock (31.7%), shoes with diverse sizes according to shoes width (13.7%), and shoes made of soft materials in consideration of various foot shapes. 2. Results of Foot Measurement Experiments Busan's males in their 60s and above were 166.31cm (Height), 63.51kg (weight), 23.94cm (foot length), 9.75cm (foot width), and 24.26cm (instep girth). The big toe angle of old males was $11.22^{\circ}$ and the little toe angle $14.70^{\circ}$. Four foot types were classified: 1 (long big foot), 2 (small inside-developed foot), 3 (toe-tip-gathered foot), and 4 (thin flat foot).

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. In order to choose suitable shoes for feet, the foot size and shape must be considered, so it is essential to grasp the exact size and shape of the foot. This study aims to present fundamental data on shoes' easy order prototype development for choosing shoes of good wearing comfort, by classifying feet size and shape junior high school boys in the early adolescent period. The subject were 234 Korean junior high school boys age from 14 to 16 years old. The subjects were directly measured anthropometrically and indirectly analyzed photographically. 6 factors were extracted through factor analysis and those factors comprised 79.42% of total variance. The factors characterizing foot girth and width, foot length, foot height, foot shape around the fifth toes, angle of foot breadth and foot shape around the first toes. 3 clusters as their foot shape were categorized using 6 factor scores by cluster analysis. Type 1 was characterized by long large foot with deformed first toe. Type 2 had smaller in foot girth, width and length than other types and with deformed fifth toe. Type 3 had average size and high foot shape. Shoes prototype which is to be developed later on will be able to generate 2D flattening in the foot sole form. Therefore, it would be a great support in producing and choosing appropriate shoes if forms are classified by subdividing foot form classification and extract a factor which shows only the foot sole shape.

The purpose of this study is to analyze the effects of both various shoe types and bare feet on ground reaction force while walking. Ten first-year female university students were selected. A force platform(Kistler, Germany) was used to measure ground reaction force. Six types of shoe were tested: flip flops, canvas shoes, running shoes, elevated forefoot walking shoes, elevated midfoot walking shoes, and five-toed shoes. The control group was barefooted. Only vertical passive/active ground reaction force variables were analyzed. The statistical analysis was carried out using the SAS 9.1.2 package, specifically ANOVA, and Tukey for the post hoc. The five-toed shoe had the highest maximum passive force value; while the running shoe had the lowest. The first active loading rate for running shoes was the highest; meanwhile, bare feet, the five-toed shoe, and the elevated fore foot walking shoe was the lowest. Although barefoot movement or movement in five toed shoes increases impact, it also allows for full movement of the foot. This in turn allows the foot arch to work properly, fully flexing along three arches(transverse, lateral, medial), facilitating braking force and initiating forward movement as the tendons, ligaments, and muscles of the arch flex back into shape. In contrast movement in padded shoes have a tendency to pound their feet into the ground. This pounding action can result in greater foot instability, which would account for the higher loading rates for the first active peak for padded shoes.

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.

PURPOSE: The purpose of this study was to compare muscle activation of the trunk and lower limbs of subjects wearing high-heeled or flat shoes while crossing over obstacles of different heights. METHODS: Twenty subjects participated in this study. While wearing high-heeled shoes (7 cm) or flat shoes (0 cm), the subjects were asked to cross over obstacles of different heights (10%, 20%, and 30% of their lower-limb length). Muscle activation of the trunk and lower limbs with the supported side while crossing over obstacles of different heights was measured using the electromyogram (Noraxon, DTS, Germany). Two-way repeated ANOVA was used to compare the muscle activation between high-heel shoes and flat shoes while crossing over obstacles of different heights. All statistical analyses were performed using SPSS ver. 21, and p-values less than .05 were used to identify significant differences. RESULTS: As an obstacle's height increased, muscle activation of the trunk and lower limbs with the supported side was increased while wearing either type of shoe, and it was generally higher while wearing high-heeled shoes. However, tibialis anterior muscle activity while wearing high-heeled shoes was lower than while wearing flat shoes. CONCLUSION: This study showed that muscle activation of the trunk and lower limbs was higher when subjects wore high-heeled shoes than when they wore flat shoes while crossing over obstacles of different heights. Therefore, high-heeled shoes can easily cause high muscle fatigue of the trunk and lower limbs, and the TA muscle may weaken in persons who wear high-heeled shoes.

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.

Objective: The aim of this study was to analyze body stability Joint coordination pattern though as bending stiffness of shoes during stance phase of running. Method: 47 male subjects (Age: 26.33 ± 2.11 years, Height: 177.32 ± 4.31 cm, Weight: 65.8 ± 3.87 kg) participated in this study. All subjects tested wearing the same type of running shoes by classifying bending stiffness (A shoes: 3.2~4.1 N, B shoes: 9.25~10.53 N, C shoes: 20.22~21.59 N). They ran 10 m at 3.3 m/s (SD ±3%) speed, and the speed was monitored by installing a speedometer at 3 m intervals between force plate, and the measured data were analyzed five times. During running, ankle joint, MTP joint, coupling angle, inclination angle (anterior-posterior, medial-lateral) was collected and analyzed. Vector coding methods were used to calculate vector angle of 2 joint couples during running: MTP-Ankle joint frontal plane. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was Bonferroni. Results: Results indicated that there was an interaction between three shoes and phases for MTP (Metatarsalphalangeal) joint angle (p = .045), the phases in the three shoes showed difference with heel strike~impact peak (p1) (p = .000), impact peak~active peak (p2) (p = .002), from active peak to half the distance to take-off until take-off (p4) (p = .032) except for active peak~from active peak to half the distance to take-off (p3) (p = .155). ML IA (medial-lateral inclination angle) for C shoes was increased than other shoes. The coupling angle of ankle angle and MTP joint showed that there was significantly difference of p2 (p = .005), p4 (p = .045), and the characteristics of C shoes were that single-joint pattern (ankle-phase, MTP-phase) was shown in each phase. Conclusion: In conclusion, by wearing high bending stiffness shoes, their body instability was increased during running.
