This is a pair of vintage Hustler Speed King roller skates. These 1940s roller skates are made of heavy metal and have adjustable leather straps with two metal pieces on the top front to hold the toe box of walking shoes for adjustable sizes. In addition, they have leather straps in the back that go around the ankle, and there would typically be extra leather padding at the back of the ankle, though for this pair, those straps are lost. They have solid metal heel plates and rounded edge footplates with heavy-duty ball bearings and fading blue wheels. They were made by the Hustler Corporation in Sterling Illinois. This line of skates was carried by wholesale, catalog premium houses, hardware, and variety stores, in addition to large chain stores throughout the country including Sears, Macy's, Montgomery Ward, Gimbels, and Marshall Field's.
