ABSTRACT

Seven different sandy soils were utilized to create three-dimensional footwear impressions from two athletic shoes (Saucony and New Balance). The footwear impressions were photographed and cast with dental stone. The impressions made in the fill dirt and the yellow builders sand retained the most randomly acquired characteristics. The impressions made in the Astatula fine sand and the crushed coquina retained the least randomly acquired characteristics. The results indicated that (1) soils with larger particles or very fine sand may retain less randomly acquired characteristics (fine detail) than other sandy soils, thus affecting the ability of the impression to retain good detail; (2) soils with higher clay or organic contents will retain more randomly acquired characteristics; and (3) impressions located in a variety of sandy soil types have the ability to retain a sufficient number of randomly acquired characteristics to effect an identification.
