A fastening system for attaching a wheel to the shoe portion of an in-line skate, which includes a pair of first and second opposing walls that depend from the shoe portion, each having a bottom edge. A pair of opposing slots formed in the walls, each having an open end at the bottom edges of the walls. A safety recess is formed on each of the first and second walls adjacent the slots. Two frame spacers each include a flange portion surrounding a raised shoulder plug. The plug and flange portions having a through-hole formed therethrough. Each of the flange portions have a safety protrusion formed thereon adjacent the plug. The plugs are inserted into the slots such that the safety protrusions removably engage the safety recesses. A wheel having an axle hole formed through its center of rotation is positioned between the pair of slots. An axle bolt is received through the axle hole of the wheel and the through-holes of the frame spacers for rotatably and removably securing the wheel between the walls of the frame.
