A toe spring and ball girth data, when marathone shoes research, development, and production in Korea, is a important point in athlete shoe research. It is clear from the results presented that any differences between MA3 and MA1, MA4 in 70%, 80% session in forepart last comparision. Especially the more 70%-80% session getting wide, the more 90% session getting up, Also, To development for high performance marathones shoes last, in all session, in korean style, 70%, 80%, and 90% session part function changed and consequently there is a need for normative last data that desribe foot, last shape, dimension. this leads to the conclusion that unique shoe lasts for both marathone shoes developmented last comparison are required for optimal marathone shoe comfort. The more ball girth construction will wide in forepart in last, the more comfort characteristic sill development. But relative with performance ability, it is need to research. The further study of Korea marathoner forefoot measurements(70% session ~ 90% session) among toe spring's angular difference of marathone last to north american and Korea marathone shoes last is required to develop and improve athletes performance in an effective way of study and to prevent forefoot injury.
