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.

Objective: This study compared the effects of streamlined shoes on dynamic gait and foot plantar pressure in healthy young adults. Background: With the importance of ankle and lower extremity mechanism, streamlined shoes are contributing to a static gait factors. However, the study of dynamic gait factor is still insufficient. Method: Sixty subjects were randomly allocated to two groups: experimental group(n=30) and control(n=30), respectively. The experimental group performed streamlined shoes, whereas the control group applied usual shoes. Main outcome measurements were assessed contact time, step length and foot plantar pressure using gait analysis with the treadmill. Independent t-test was used to compare the both groups. Results: Compared with control group, contact time of forefoot, midfoot and hindfoot decreased significantly in experimental group(p<.05), Step length increased significantly in experimental group(p<.05). Foot plantar pressure of midfoot and hindfoot increased significantly in experimental group(p<.05), whereas that of forefoot did not show significantly in experimental group(p>.05). Conclusion: Our findings suggest that streamlined shoes was more effective than usual shoes in dynamic gait change including contact time and step length and foot plantar pressure in healthy young adults. Application: The results of streamlined shoes might help to control for the gait of industrial workers.

Recently, the development of design of cultural goods is focusing on excessively workmanship-oriented craft items. However, an advanced strategy that is practical and develops market-oriented goods in the world needs to be suggested from now on and the selection of goods item aimed to world market is very urgent. Therefore, the purpose of this study was to design practical and worldwide market-oriented shoes with Korean traditional image as a cultural goods. As software tools, 2D Adobe Illustrator Adobe Photoshop and 3D MAX 8.0 Photoshop CS were used to design the shoes. From 8 types of pattern design to which Koran traditional pattern was applied and 7 types of shoe design to which Korean traditional shoes were applied, 60 types of planar shoes design coating developed pattern designs were made. Furthermore, 3D design of cultural goods of shoe made possible to observe it three-dimensionally and accurately from the top, the front and the side respectively. Finally, 43 types of cultural goods of shoe to which Korean traditional shoes were applied were designed successfully according to traditional patterns and colors. The systematic database was established based on the developed pattern design of the shoes and might make the best use of the development of related design of cultural goods. Although there were partly some limitations in the aspects of design and material development of Korean traditional shoes, this study would help the economics of shoe industry in Korea producing high value-added products.

The purpose of this study was to analyze impact absorption function of midsole in cushioned marathon shoes. The foot is made up of a complex interaction of bones, ligaments, and muscles. These structures help the foot alternate between being a mobile, flexible adaptor and a stable rigid lever. The foot is broken down into two functional parts, the forefoot and the rearfoot. Cushioned marathon shoes for high arches have generous cushioning for efficient and high-mileage runners. Cushioned marathon shoes are made for feet that have high arches or no excessive motion and don't roll inward or roll outward. This condition is known as underpronation. Especially, Cushioned marathon shoes are designed to reduce shock and generally have the softest (or most cushioned) midsoles and the least medial support. They are usually built on a semicurved or curved last to encourage foot motion, which is helpful for underpronators (who have rigid, immobile feet). Cushioning marathon shoes recommended for the high-arched runner, whose foot may roll outward (supinate) rather than the natural slight inward roll, or whose feet may be relatively rigid. Cushioning shoes emphasize flexibility and usually are built on a curved or semicurved last to encourage a normal motion of the foot. Cushioning shoes usually offer no medial (inner foot) support. Cushioned marathon shoes have the single-density midsole, which is stable and relatively firm for a cushioned shoe, stays the same. But the forefoot is more rounded, and the rearfoot now includes a new and supportive rearfoot cradle. A foam midsole, perhaps with layers of different densities, to provide cushioning and shock absorption. EVA (ethylene vinyl acetate) and PU (polyurethane), the materials from which these foams usually are made. EVA is slightly softer than PU. EVA and PU may be layered together in a shoe, or a shoe may have more than one density of EVA.

This study was conducted to identify the effects of high-heel shoes on EMG activities of rectus femoris and biceps femoris in 28 healthy women. Subjects were composed of experimental group (wearing high-heel shoes) and control group (wearing low-heel shoes). Two groups participated in three conditions standing (bare foot wearing athletic shoes and 7.5 cm height shoes). In high-heel shoes condition, EMG activities of rectus femoris of control group were significantly lower than that of biceps femoris of experimental group, but EMG activities of both muscles of experimental group did not should significant difference. In bare foot standing condition, EMG activities of rectus femoris of experimental group were significantly lower than that of biceps femoris but EMG activities of both muscles of control group had no significant difference. These results showed that hamstring lengthening effects was produced when wearing high-heel shoes because the external knee extension moment was increased. In the short term, high-heel shoes effect on the increase of the biceps femoris activities by spindle reflex, but in the long term, the normal amplitude of the same muscle activities by Golgi tendon organ reflex.

This study aims at analyzing the formativeness of women fashion shoes shown in the high fashion since 2000 along with the necessity of study for such purposes. Fashion shoes designed for the perfection of high fashion have been positioned as an important item to increase the value of fashion. Subsequently, three formative images through the research method under the literature study could be analyzed as follows. First, the Fetishism image appeared from 18th century and the shoe heel has the erotic internal beauty while attracting the erotic nature from the perspective of 'feet confinement'. The high heel came to have an absolute relationship with the feminine beauty, and the feet and shoes are accepted for the erotic symbol regardless of anyone in the East or West. Second, the fashion shoes in the Maximalism image to pursue for the dream and excitement at the same time have been shown at the same time by using various ornaments in an exaggerated manner for the use of ornaments to clothes through designs by shoe designers. Third, the Aristocratism image in the fashion shoes was remarkably highlighted with the use of materials from processing natural materials with the best quality, which was expressed in an exotic manner with roughness and comfort despite the nature of refinement balanced with the simple reactionary tendency and technical senses of handicrafts. It can be perceived that the inner emotions of human beings are expressed by intentionally dismantling the functions of shoes in terms of functionality even in the fashion shoes in completing the ideal images after which are pursued by people.

Purpose: The purpose of this study is to compare kinematics and kinetics on the knee joint between stair gait with unstable shoes and barefoot in healthy adult women. Methods: Seventeen healthy adult women were recruited for this study. The subjects performed stair ascent and descent with unstable shoes and barefoot. The experiment was repeated three times for each stair gait with unstable shoes and barefoot. Measurement and analysis of the movements of the knee joint were performed using a three-dimensional analysis system. Results: Statistically significant differences in the knee muscle force of semimembranosus, biceps femoris-long head, biceps femoris-short head and sartorius, patellar ligament, medial gastrocnemius, and lateral gastrocnemius were observed between unstable shoes and barefoot gait during stair ascent. Statistically significant differences in the knee muscle force of sartorius, rectus femoris, medial gastrocnemius, and lateral gastrocnemius were observed between unstable shoes and barefoot gait during stair descent. Statistically significant differences in the knee flexor moment of semitendinosus, biceps femoris-long head, biceps femoris-short head, sartorius, rectus femoris, vastus intermedialis, medial gastrocnemius, and lateral gastrocnemius were observed between unstable shoes and barefoot gait during stair ascent. Conclusion: Therefore, wearing unstable shoes during stair gait in daily life is considered to influence knee joint kinematics and kinetics due to the unstable shoes, and thus suggest the possibility that reducing the risks of pain, and knee osteoarthritis, stabilizing the knee joint caused by changes in the loading of the knee joint.

Objective: The purpose of this study was to investigate the impact of wearing various types of shoes on gait ability in stroke survivors and in order to gain information in regards to shoes that could possibly replace ankle orthosis. Design: Cross-sectional study. Methods: Eight hemiplegic survivors diagnosed with stroke participated in the study. Gait was analyzed using the GAITRite Electronic Walkway (CIR System Inc., USA) when subjects walked with no showed, walked with non-ankle-covered shoes, and walked with ankle-covered shoes. This study collected gait variables, including velocity, cadence, step length, stride length, single support time, and double support time, respectively. Results: In the comparison of walking with no shoes, non-ankle-covered shoes, and ankle-covered shoes, there were significant differences in gait velocity, step length, stride length, and the less affected side single support time (p<0.05). However, there were no significant differences in cadence, affected side single support time, and double support time. Conclusions: Ankle-covered shoes had a positive impact on the gait of stroke survivors. However, it is necessary to conduct more studies comparing various types of shoes with ankle orthoses.
