A study of preparing rubber soles and heels was made to improve the quality in their physical properties such as resistance of cut-growth, abrasion resistance and tensile strength. Following results were obtained in the characteristics of rubber compounding: 1. In the reinforcement effect of fillers, it was found that hydrous silcate and carbon black were the best, aluminum and calcium silicate were pretty good, and basic magnesium carbonate was moderate. 2. SBR/BR blend in the ratio of from 85/25 to 100/0 and NBR/BR blend in the ratio of from 60/40 to 20/80 were the most suitable compounding condition.
