Abstract: An adjustable roller skate toe stop converter is provided for a roller skate having a toe stop mounting shoulder defining a threaded toe stop mounting bore of a first predetermined diameter adapted to receive and threadingly engage a threaded mounting stud of a first toe stop. The converter converts the skate for use with a second toe stop having a threaded mounting stud of a diameter larger than the mounting stud of the first toe stop. The converter comprises a generally cylindrical block having on one end a small bore and on the other end a large bore, the large and small bores communicating in coaxial alignment to define an annular shoulder between them. A bolt is introduced into the block and is threaded into the toe stop mounting bore of the roller skate to mount the block thereagainst with the head of the bolt bearing upon the annular shoulder in the block.
