Objective: Shoes midsole are crucial for reducing impact forces on the lower extremity when someone is running. Previous studies report that the cushioning of running shoes make it possible to use less muscular energies. However, the well cushioned shoes result in energy loss as the shoe midsole is compressed. Cushioning reduces the load on the body, it also results in the use of more muscle energy to create propulsion force. The purpose of this study was to investigate the effect of the difference of shoe hardness & resilience on the running.

Results: In vastus lateralis muscle Activation, Type 55 were significantly higher for Type 50 and X (p=0.019, p=0.045). In Gluteus Maximus muscle activation, Type 55 was significantly lower for type 50 (p=0.005). In loading late, Type 55 and X were significantly higher for type 45 (p=0.008, p=0.006). Conclusion: The components of a shoe are very complex, and there can be many differences in manufacturing as well. Although some differences can be found in the biomechanical variables of the high elastic midsole, it is difficult to interpret the performance enhancement and injury prevention.
This study is aims to study the background of how the shape of the wooden shoes developed and worn by Koreans and Japanese in the ancient times by sorting and examining the types and shapes. Relevant bibliography, which are mainly related to the excavated wooden shoes from 3 B.C.E to C.E. 8., were used as research materials. The formation of wooden shoes required easy access to raw materials -which is trees- for production. According to the analysis, both Korea and Japan made the flat wooden shoes using cuboid wood. Both countries bore a hole on a specific location to distinguish the right foot and left foot, however the style of the heel was different in the two countries. The slip-on(Undu-hyeong) wooden shoes were also common in both countries. The slip-on had no-heels and was made by digging-out a piece of the cuboid wood. Some slip-ons made by the Japanese had furrows on the bottom, and they were known to make different types of the slip-on wooden shoes depending on the purpose. Observation of the wearing methods show that commonality can be found between the wooden shoes of Korea and Japan, and this indicates that cultural exchanges between the Silla/Baekje and Japan took place from the 4th to the 6th century. Also, the flat wooden shoes in Japan developed rapidly, as the shoes became an integral part of its life and culture, which was closely tied to agriculture. Eventually, due to the difference in climate and life-style, the slip-ons became the primary type of wooden shoes in Korea, while the flats became the main type of wooden shoes in Japan. It is, however, clear that as the relationship between the two countries became closer, the cultural exchanges regarding the wooden shoes were considerable.
The purpose of this study was to analyze the wearing pattern and design preference of shoes for men, and to develop the possibility and strategy of the shoes market for the shoes marketers and manufacturers. In this study, the data obtained from 285 respondents were analyzed by the descriptive statistics. The results from the data were as follows : The most frequent brand among the 45 shoes brand by 285 respondents described in free style was 'Esquire'. The 268 respondents possessed two shoes or more, the most frequent shoes' color was black, and the most preferred brand was 'Kumkang'. The 195 respondents indicated the discomfort of ready-made shoes, The 198 respondents discarded their shoes 'on the reason of worn-out', the 98 respondents indicated that the most important thing in the purchasing point was 'the comfort of shoes' The respondents preferred shoes with 'slip-on type', 'cow leather', 'semi-rounded toe', 'no-metal ornaments', 'moccasin tip', 'leather-sole', and '3cm heel'. Finally, this study proposed that the best strategy for shoes marketers and manufacturers was to upgrade the comfort of shoes by design(line) and the material with functional textures.

The purpose of this study was to compare the ground reaction forces and plantar pressure variables among three different safety shoes (Type 1: ergonomically designed and high quality shoes, 2: curved and cushioned safety hoes, and 3: regular safety shoes) and to find the effect of insole during walking. Ten healthy subjects were recruited for this study. The ground reaction force was measured using a 3 dimensional motion analysis system. Plantar pressures were measured Pedar Mobile foot pressure scan system. The ground reaction force variables were not significantly different among three different shoe types and insole conditions. After insertion insole, plantar pressure distributions were improved. These results suggest that the type 1 safety shoes was superior than other safety shoes in the statistics, and applying insole could be a possible method to prevent fatigue of lower extremity and musculoskeletal disorders. Further studies are needed to find the effect of ergonomically designed safety shoes design and insole on practical value prevention of musculoskeletal disorder, fatigue and satisfaction of workers.
Purpose: To investigate the characteristics of the patients and therapeutic shoes for diabetic patients. Materials and Methods: Forty two diabetic patients who had their own therapeutic shoes which were prescribed somewhere else were studied from March 2003 to December 2003. There were 27 males and 15 females, and the mean age was 62.1 years (range, 49-72 years). Duration of diabetes was average 14 years (range, $6{\sim}30$ years), all had type 2 diabetes. Sensation was examined with 5.07 nylon monofilament. The route of purchasing the shoes, compliance to the prescribed shoes were investigated by interview. The shape of shoe, stiffness of upper, conformity of insole to the shape of the foot were recorded. In-shoe plantar pressure was measured in 15 patients. Results: Eighteen patients were insensate to the monofilament. Seven patients did not wear the therapeutic shoes, and only 18 of 35 patients were wearing the therapeutic shoes more than 6 hours a day. The shoes of 17 patients were prescribed by medical doctor and the rest were purchased by the recommendation of acquaintances or advertisement. Ulcer recurred in four of five patients to whom the shoe was prescribed by medical doctor and the cause of three recurrences were evident by just observing the foot and shoe. The therapeutic shoes were made from 11 different makers. Eight shoes were adequate for diabetic patients with respect to the material, shape of insole, type of shoe. In-shoe plantar pressure was examined in 15 patients and was less than 300 kPa in all patients. Conclusion: The therapeutic shoes for the diabetic patients need to be prescribed by medical doctor for selective patients with neuropathy or previous history of ulcer and follow-up examination is important to monitor the compliance of the patients and adequacy of the shoes.
Objective: The purpose of this research is to examine the effects of three types of different running shoes with different properties on impact variables (PVRGF and VLR) and the lower extremity joint's dynamic stability variables (LyEs of DPA, IEA, FEA, DPAV, IEAV, and FEAV) during running. Method: The participants in this research were 12 males (Age: 22.0 ± 3.3 years, Height: 177.2 ± 4.1 cm, Weight: 74.3 ± 9.6 kg). One type of N company's running shoes and two types (FA, FB) of F company's running shoes were used. As for the properties of the running shoes, thickness (mm), dwell time (ms), peak acceleration (m/s2), and energy return (%) were measured. The motions running at 3.5 m/s on a treadmill (Instrumented treadmill, Bertec, USA) wearing each type of running shoes were analyzed. Results: Although the VLR of the thick running shoes (FB) was smaller than that of the other running shoes (N, FA), the LyEs of PVGRF and DPA were larger (p<.05). Even though the running shoes' dwell time (i.e., impact absorption time) and peak acceleration showed a positive correlation with the LyEs of DPAV, IEAV, and FEAV, the energy return showed a negative correlation (p<.05). Conclusion: Our results indicated that the running shoes with excellent impact absorption function are predicted to be suitable for running beginners who need to reduce the burden of the lower extremity joint during running. The running shoes with excellent energy return are expected to be suitable for mid-and long-distance running elite athletes or marathoners to whom stability and consistency are essential during running.
The purpose of this study Is to classify foot types of elderly women and young women and to suggest shoes size system by foot types for elderly women. The subjects were 321 elderly women and 181 young women. Their right feet were measured directly and indirectly by using scanner and digital camera. The anthropometric measurements were composed of 62 items. They were measured during the months of July and October in 2001 and November in 2002 The results and discussions of this study are as follows. First, in analyzing shape of the foot of elderly and young women, the shapes of foot were classified as N-type (high and narrow foot shape and wide toes), W-type (wider width for its length and severe alteration), L-type (low foot shape as oval). Second, the most characteristic foot type in elderly women was W-type. In this type, the width was wider for its length, the first metatarsophalangeal protrusion was severe and the toes were gathered at the center. On the other hand, young women belonged to N-type. Third, we suggested new size system of shoes for elderly women and the standard foot shape each type. The size system was based on foot length and foot types. Hopefully, understanding the shapes of foot and characteristics of each foot type will help to develop suitable shoes for elderly women.
The purpose of this study was to investigate the emotion and preference for shoes styles through empirical research, in accordance with personality type, age and fashion innovativeness of female students. This study was a survey research through convenience sampling of 224 college students. In order to select shoes style, a pre-classification through dictionary and online search was done to choose the representative eight styles of shoes to college students. Personality types was determined from the modified measures of the brief MBTI to fit this study, and the emotional scale of sensibility was revised from the previous studies. SPSS statistical analysis were executed as follows: First, preference and emotion on shoes styles were significantly different in accordance with the shoes type and the diagram from the results of correspondence analysis showed some relationship between the sensibility and shoes styles showing 4~5 clusters. Second, the sensibility and preference had significant difference in some type of shoes according to the personality types of college students. Third, there was a significant difference in the shoes preference and sensibility by accordance of the degree of fashion innovativeness. And there was a significant difference in preference of shoes according to the purchase frequency of consumers. We hope this data is useful to this current dynamic market of shoes to the both sides of producer and consumers.

This research attempted to examine whether there were differences in preference for the shoes according to fashion lifestyle and age by conducting survey on 200 women of 20s and 40s among the adult women who were expected to have interest in not only functionality but also aesthetic aspects of shoes. First, the results of comparing the preferences according to fashion lifestyles showed that those who pursued practical group preferred loafer, strap shoes, and baggy boots, indicating that they preferred low and comfortable shape of shoes which are easy to put on/take off and easy to coordinate with any clothes. Those who pursued personality group and ostentation group were more sensitive to fashion than practical group preferred high heel shoes, which could express their own personality, it would be great to have various designs by reflecting the trendy materials and details focusing on pumps, strap and walker boots which can express individuality and supplement the body shape and height as matching to the trendy clothes. Second, as women in 20s have tendency to show more preference of a certain trendy shoes shape than women in 40s, the shoes designs for 20s should focus on certain types of shoes preferred by them by varying materials and details, rather than having various designs. However, it would be great to show various designs for the shoes for 40s. Most of the 20s are the individual and complex fashion-seeking types while the 40s have the most of practical fashion-seeking type and the least of individual fashion-seeking type.
Objective: The purpose of this study was to analyze and compare different kinds of outdoor walking shoes in terms of muscle fatigue and ground reaction force on walking, and to provide foundational data for developing and choosing outdoor walking shoes that fit the users. Method: The study subjects were 30 healthy men. The experiment was conducted by using outdoor walking shoes with different inner and outer harnesses of the midsole, and shapes of the outsole. For data collection, electromyography was used to measure the muscle fatigue of the anterior tibial muscle and gastrocnemii, which contribute to the dorsiflexion and plantarflexion of the ankle joint, and the biceps muscle of the thigh and lateral great muscles, which contribute to the flexion and extension of the knee joint. A GRF measurement device was used to measure the X, Y, and Z axes. Results: In the type A outdoor walking shoes, regarding the hardness of the midsole, the inner part was soft, while the outer part was hard. The vertical ground reaction force was the lowest, which means least impact while walking and light load to the knees and ankles. The type C outdoor walking shoes were intended to provide a good feel in wearing the shoes. The tibialis anterior, biceps femoris, and gastrocnemii indicate low fatigue, which means that during a long-distance walk, it will minimize the fatigue in the muscles of the lower limbs. Conclusion: To sum up the study results, the different types of outdoor walking shoes indicate their unique characteristics in the biomechanical comparison and analysis. However, the difference was not statistically significant. Thus, a systematic and constant follow-up research should be conducted to cope with expanding market for outdoor walking shoes. Lastly, this study is expected to present foundational data and directions for developing outdoor walking shoes.
