본 연구의 목표는 새로 개발된 구두골을 평가하여 보다 편리하고 기능성이 향상된 구두를 제작할 수 있는 한국형 구두골(shoelast)을 설계하는 것이다. 구두의 적합성에 영향을 주는 인자를 찾아내고, 이들에 대한 평가 방법을 개발하여 인간공학 실험을 실시하였다. 새로 개발한 구두골은 남.여 각각 2 개의 타입(type)으로 10 명의 평가자에 의하여 단기간 (1 주일)의 착화감 평가가 이루어졌다. 인체측정치와 발 부위의 상관성 평가, 피험자 각각에 대한 시계열분석의 결과를 종합하여 두 타입의 구두골에 대한 문제점을 파악하고, 그 개선점을 도출하였다. 이 결과를 바탕으로 한국형 구두골(shoelast) 설계 치수를 설정하였다. 본 연구에서는 얻어진 결과는 구두 제작 공정에 직접 사용될 수 있으며, 구두의 쾌적성 및 기능성 향상에 크게 기여할 것으로 기대한다.

The purpose of the present study is to find design factors that have an effect on man's foot, and to develop an optimal last for man's functional shoe design based on these factors. Analyzing 4000 men's foot data, three men were selected for fitting test with the last and shoes manufactured in the present work. Based on the results of the fitting test, the modifications of last for the optimal design have been made using CAD/CAM technologies.

Shoes adding layer for preventing sprain and slippery for the elderly were developed using the shoe-last based on the Korean anthropometric elderly. The anthropometric elderly, arbitrarily defined as those 65 years of age and above, were a distinct with special needs. The shoe-last for the elderly was also designed in this paper. A total of 9 subjects participated and evaluated each shoes made by developed shoes-last and adding layer for preventing sprain and slippery. As results, the proposed shoes have the better functions for preventing sprain and slippery compared to others.

발의 구조는 사람에 따라 약간의 차이를 보이기는 하나 일반적으로 중앙을 기준으로 할 때 비대칭적(Asymmetric)인 구조를 보인다. 특히 동양인의 경우, 비대칭성에 의한 발의 좌우 편차는 서양인에 비해 큰 것으로 알려져 있다. 따라서 발 길이 뿐만 아니라 발 둘레, 발 높이, 볼 거스(Ball girth) 등을 고려할 경우 발의 형태는 더욱 다양해지며, 이를 고려한 족형의 개발은 신발 설계에 있어서 필수적으로 요구된다 하겠다. 이 논문은 전국 남녀 8000명의 좌, 우 발의 각 25개 부위 측정한 후 전문가들의 조언을 통해 가장 구두골 제작에 영향을 주리라 생각되는 발의 10개 중요 부위를 이용하여 현재 단순히 유아용, 아동용, 학생용, 성인용으로 구분되어진 구두치수를 Classification 기법을 사용하여 연령별로 적절하게 구분되어 구두를 개발할 수 있도록 하였다.

The purpose of this study is to develop Korean shoe-last based on the conformability of shoe. For this work, the important dimensions for the conformability of shoe were investigated and the systematic methods for evaluating the comfortable shoe were developed. Different two types of shoe-last for men and women were used in the experiment, respectively. 8000 feet dimensions of Korean adults were analyzed for developing standard shoe-last in this study. A total of 10 subjects (ranged from 21 to 25 years old) participated voluntarily. They evaluated each shoes made by developed shoe-last. A rating scale and description was used to express the degree of conformability. Also, 26 feet dimensions were measured using martin-typed gauge and footprint. The relationship between foot dimension and conformability of shoe was analyzed. As a result, Korean standard shoe-last was suggested based on the based on the conformability of shoe. The evaluating methods will be expected to help designer find more important design parameters. We will also expect that the standard shoe-last guarantee the optimal gait and minimal workload, especially in aspect of conformability.

This study is a basic study to develop shoe last design technology to enhance and revitalize the competitiveness of the handmade shoes. In-depth interviews were conducted with four manufacturers in Seongsu-dong to identify the production status and design technology of shoe lasts. The result of the research is as follows. Firstly, shoe lasts for adults are produced at intervals of 5mm between 245mm-285mm for men's shoes, and between 220-260mm for women's shoes. The production rate of women's shoes was high in the order of general type, boot type, and sandal type while men's shoes mainly produce general type. Secondly, the master last size and ball girth rating for men's and women's shoes were analyzed to EE-EEE grade at 260mm and D grade at 235mm. The length of the master last for men's shoes is 276-290mm, the heel width is 60-65mm, the ball width is 88-90mm, the ball girth is 250mm, and the waist girth is 248mm. The length of the master shoe last for women's shoes is 236-245 mm, the heel width is 50-55mm, the ball width is 78-80mm, the ball girth is 211~213mm, and the waist girth is 213~215mm. Thirdly, the last grading deviation is 5mm in length, the heel width is 0.5mm, the ball girth is 3.5mm, and the ball with is 1.2mm. The ball girth dimensions of Oxford type, slip-on type, and sneakers type are made at 250mm, 248mm, and 245mm for men's shoes. For women's shoes, the ball girth dimensions of pump type, loafer & boot type, and sandal type are made at 211~213mm, 214~215mm, and 211mm. Fourthly, t+he construction of the automation system is insufficient and almost completely depends on manual production.
