Abstract: A shoe skate includes a single row of in-line wheels or rollers, mounted on the shoe as front and rear wheel units. The front wheel unit includes a bogie pivoted about a transverse axis and carrying leading and trailing wheels, enabling the skater to maintain these wheels in contact with the skating surface where the heel of the shoe is raised. The rear wheel unit is mounted on the heel of the skating shoe. A leaf spring bears on the opposite ends of the bogie, to maintain the bogie in a normal stable condition relative to the shoe.
