An in-line skate is disclosed having a rigid frame with a platform and having a boot with a shell. The shell includes a sole. Two longitudinal parallel rails extend downwardly from a lower side of the platform. A plurality of in-line skate wheels are secured to the frame. An upper side of the platform has first, second and third recesses in toe, heel and intermediate portions of the platform, respectively. A lower side of the sole of the boot has first, second and third projections in toe, heel and intermediate portions of the sole, respectively. The first, second and third projections of the sole matingly engage the first, second and third recesses of the platform, respectively, when the boot is coupled to the frame. Fasteners secure the boot to the frame at the first, second and third recesses of the frame. A block is disclosed including top and bottom sides. Sidewalls extend between the top and bottom sides. The block is supported between the longitudinal rails of the frame and is positioned between outer circumferences of two adjacent wheels. The block is spaced from each of the two adjacent wheels. A fastener is included for mounting the block to the frame and is entirely contained between planes defined by the longitudinal rails of the frame.
