An in-line skate for a child comprises a boot and a frame which enables size adjustment whilst tightening is effected in two ways to ensure the structure does not easily loosen in use. The frame is formed in two halves (A, B) with an insertion block (19) and a platform (14) providing holes (20, 15) respectively for a boot- securing rivet (60) and a bolt (62). The boot is formed in four parts, toe section (31) having wing plates with side slots (32, 33), heel section (36), cuff section (42) and latch section (50). The toe section (31) is adjustably positioned longitudinally relative to the heel section (36) by preferably a sawtooth interaction (Fig 2, not shown), and then the boot tightened to the frame by rotation of adjustment rod 16 assisted by sloping sides (21) of insertion block (19); the restoring force of spring (17) is utilised when untightening. The latch section includes another adjustment rod (52) associated with a pivoted latch plate (53) so that the whole assembly of toe, heel and cuff sections can be loosened or tightened, the rod (52) passing through thread holes (45) in the cuff section (42), thread holes (41) in the heel section (36) and the slots (32, 33) in the wings of toe section (31) to rivet plate (54).
