<p>PROBLEM TO BE SOLVED: To provide a clogging prevention sole having such a structure as to, even when a wearer tramples excrement of livestock or the like, prevent the sole from being clogged up or, even when the sole is clogged up, quickly remove it therefrom, and a boot for stock-raising sites using the same, being used at a stock-raising site, or to provide a sole having such a structure as to, even when a wearer tramples lard or the like, prevent the sole from being clogged up and, even when the sole is clogged up, quickly remove it therefrom, and a boot for food manufacturing sites using the same, being used at a food manufacturing site.SOLUTION: The clogging prevention-structure sole includes a first continuous wavelike convex design structure with a wavelengthλin the width direction of the sole from one end to the other end of the sole, the wavelengthλbeing 1/8-1 of the maximum width of the sole in the width direction. A grounding surface as a surface of the convex design structure is a plane. The clogging prevention-structure sole has a design height h of 3-8 mm, a design width w of 3-8 mm, a design gradientαof 0-10°, and an angleβof the wavelike shape of 0-45°, and the first and second wavelike convex design structures are similarly provided on the entire sole at prescribed intervals s (9-14 mm) apart from each other.</p> |
