This study investigates the size marking differences in domestic and international cycle wear brands offered in Korea and provides basic material to develop a size system for cycle wear suitable for the Korean somatotype. Study methods include size systems suggested in the web-sites of domestic and international cycle wear brands offered in Korea. Brands used for the study included 8 brands (3 domestic brands, 2 Italian brands, 1 Australian brand, 1 Swiss brand and 1 Japanese brand). The results of this study were as follows. Domestic brand A company marked the size from 85 to 110 based on height(cm) and weight(kg) and indicated the actual size of the product for customers to refer to. Domestic brand B company marked the size from ES:85 to 2XL:110 based on height(cm) and weight(kg), Domestic brand C company marked unisex size from XS to XXL based on weight(kg) and height(cm) and waist circumference(inch)with a separately marked women size XS-M. Italian brand, D company marked size from S-4XL for men based on height, chest, waist, hip circumference size(cm) and XS-2XL for women. Italian brand F company marked size from S-3XL for men and XS-XL for women based on chest, waist and hip circumference size(cm). Japanese brand G company marked size fromS-3L for men based on height, chest, waist circumference size(cm) and S-XL for women based on height, chest, waist and hip circumference size(cm). Australian brand H company marked sizes as XS-XXL based on chest circumference size(cm) for upper clothes for men and for women XXS-XL. For bottom clothes, they marked sizes XS-XXL for men based on waist circumference size(inch) and XXS-XL for women based on waist and hip circumference size(inch). Swiss brand, I company marked men sizes as XS-XLG and TIR based on a chest circumference size(cm) based on height(cm) for bottom clothes and chest circumference size(cm) for upper clothes with XS-XL for women based on a hip circumference size(cm) for bottom clothes and chest circumference size(cm) for upper clothes. In conclusion, domestic brands have a wide range of sizes and utilize a range of weight against height to cover various body somatotype. The Italian brand indicated that S size is bigger than other brands when it comes to deviation and a relatively small size tolerance with each size. Japanese brands have a well-organized size system based on height and basic body measurements. Australian brand are variously distributed without regular dimension tolerances for each size and Swiss brands have bigger round sizes. The investigation of size marking for domestic and international cycle wear showed that cm and inch are combined and that each country has a different size system with significant difference in dimension and size deviation. Thus, there is a need to establish standards and develop a domestic size system for international cycle wear and the purchase of overseas brands. However, it has the limitation in generalization of results because there is a little investigation brand.

Seniors have more economic power, leisure time and better health compared with the past; in addition, there with increased social activity opportunities that allow for active and independent consumption activities based on their economic independence. Therefore, the silver industry for elderly consumers is buoyant in the development of product planning and marketing strategies that target seniors. It is necessary to know the exact characteristics of advanced age along with feet studies that provide basic information on the shape of shoes; however, there are few studies on elderly men's feet. This study develops a shoe sizing system for elderly men based on previous studies which analyzed the aspects of sole shape for individuals aged 60 or over. The distribution on KS G 3405 (2001) was examined and basic items were selected based on a correlation analysis of items related to foot shape. The measurement interval was based on KS and cross analysis was conducted for basic items to select an interval which indicated a frequency of more than 5% by type with a measurement system established by type. The results of the study are as follow. A sizing system was developed with an interval of 5 mm for foot length, an interval of 3 mm for the circumference of the top of the foot and an interval of 6 mm for the circumference of the top of the foot within the same foot length standard to develop a shoe sizing system for elderly men. The respective sizing systems in accordance with type were developed and 12 types of sizing systems were suggested for elderly men to reflect characteristics by type. The differences in sizing system were compared by combining sizing systems by type of sole for elderly men. Type H consists of the greatest number of foot length sections using 7 sections of foot length at 235-265 mm, Type A consists of 6 sections of foot length at 240-265 mm and Type V and D consist of 6 sections of foot length at 235-260 mm. The circumference of the top of the foot has 7 sections from C to F; Type H and A consist of C-EEEE and Type V consists of 6 sections of D-F, and Type D consists of 5 sections of D-EEEE. Type H and A include the sections of small circumference of the top of the foot; however, Type V includes the sections of large circumference of the top of the foot and Type D includes the section of small foot length and a large circumference that indicated differences between type. Type H, subtype 1 (the frontal part of the foot is high and the central part of the foot is low) and 2 (the frontal part of the foot is low and the central part of the foot is high) shows the distribution of size appellation in the sections of C-D where the circumference of the top of the foot is smaller than subtype 3 (the frontal part of the foot is low and the central part of the foot is low) that indicated that the size table is suggested with the reflection of size appellation only for Type H of small width and large height. Appellations are classified in accordance with 3-dimensional type in the section less than 240 mm of foot length. Type V show the same distribution of the appellation (including the section of D-EEE) for all the three types, except for a part of the section of 260 mm. The size appellations of subtypes 2 and 3 are distributed in section F, which indicates the formative characteristics of the foot with a large width or height. Type A has differences in appellation distribution between 3-dimensional types; subtype 2 is distributed in the small circumference section and indicates that Type A has the foot shape with a small width and high height. The distribution of size appellation of subtypes 3 and 1 with the section of large circumference suggests that subtype 3 of Type A (the foot shape with the largest width) has no large foot length and subtype 1 has a large foot length. Type D has differences in appellation among three subtypes, but all of them are included in subtype 1 and suggests that the subtype 1 sizing system can be used. The results indicate that a shoe sizing system for elderly men by foot type could improve the suitability of shoes and provide a wider range of size and satisfaction that helps shoe makers produce shoes of various purpose and function for seniors.
