An in-line skate apparatus has a frame for attachment to the sole of a shoe with a pair of outer, substantially flat side faces, a front end, a rear end, and a lower edge. A plurality of wheels are rotatably mounted on the frame in a line from the front end to the rear end of the frame, and a cut out extends upwardly from the lower edge between an adjacent pair of wheels. A separate H-block is releasably mounted in the cut-out so as to substantially fill the cut-out, and has a width at least equal to the width of the frame, so that its outer side faces are substantially flush with the outer side faces of the frame. The H-block has an arcuate, downwardly directed sliding region extending across its width and along at least part of the height of each side face, whereby the sliding region of the H-block includes the only sliding surface of the apparatus during sliding maneuvers.

1. An in-line skate apparatus, comprising: a frame for attachment t the sole of a shoe, the frame having a pair of outer side faces, a front end, a rear end, an a lower edge, and being of predetermined width between said outer side faces; a plurality of wheels rotatably mounted on the frame in a line from the front end to the rear end of the frame; the frame having a cut out extending upwardly from said lower edge between an adjacent pair of wheels; a separate H-block mounted in the cut-out, the H-block being of shape and dimensions matching those of the cut-out such that it fills the cut-out, the H-block having outer side faces and a width at least equal to the width of said frame, and having an arcuate, downwardly directed sliding region extending continuously across its width and along at least part of the height of each side face, whereby the sliding region of the H-block comprises the only sliding surface of the apparatus during sliding maneuvers. 2. The apparatus as claimed in claim 1, wherein the cut-out region in each plate is generally rectangular and ha a height equal to at least half of the overall height of the plate. 3. The apparatus as claimed in claim 1, including a releasable fastener device for releasably mounting the H-lock in the cut-out region of the plates. 4. The apparatus as claimed in claim 1, wherein the outer side faces of the block each have an upper, substantially flat region and at least one curved, tapered portion extending downwardly from said flat region to said lower arcuate face. 5. The apparatus as claimed in claim 4, wherein each outer side face of the block has a first, inwardly tapering portion extending at a first angle from said flat region, and a second, inwardly tapering portion extending at a second angle different from said first angle from the first tapering portion to said lower arcuate face. 6. An in-line skate apparatus, comprising: a frame for attachment o the undersurface of a shoe, the frame having a pair of spaced, parallel downwardly directed plates; a plurality of wheels mounted in-line between the plates; the plates each having n outer flat surface, and a lower edge, each lower edge having an upwardly indented, cut-out region of predetermined height between an adjacent pair of wheels; a separate H-block mounted between the side plates and aligned with the cut-out regions in the side plates, the H-block having portions extending outwardly into each cut-out region and having outer side faces including flat portions which are flush with the outer surfaces of the respective side plates, the width of the block between the outer flat side face portions being substantially equal to the spacing between the outer flat surfaces of the side plates; and the H-block having a downwardly directed, lower arcuate face extending continuously between the two plates, the lower arcuate face and outer side faces of the H-block together providing a sliding surface for sliding maneuvers.
