PURPOSE: Anti-skid shoes are provided to be semi-permanently used and to reduce manufacturing costs. CONSTITUTION: Anti-skid shoes comprise triangular adjustment pins (100, 101) which are adjusted in height, increase frictional force, and have a special pin tip. The anti-skid shoes prevent a user from slipping on an oily surface by mounting a diamond on the pin tip. The adjustment pins are manufactured in a polygonal shape. |
