<p>A rowing shoe (1) of adjustable length has a shell (2) divided into heel- and toe-sections (4, 9) carried by parts (6, 7) of an elongate chassis (5). The chassis-part (7) carrying the toe-section (9) slides on a head (21) of chassis-part 6 which is fixed to the foot-stretcher of the boat. A lever (30) pivoted on the chassis-part (7) projects forwardly from the toe-section (9) and has a slotted projection (29) engaged with one of a series of teeth (31) of the head (21) to restrain sliding of chassis-part (7). Depression of lever (30) releases the restraint by lifting projection (29) clear of the teeth (31), so allowing length-adjustment of the shoe (1) to a size indicated through a window (3) on an extension (24) of a plate (23) carried with the chassis-part (7). Release of the lever (30) allows the projection (29) to engage a tooth (31) and hold the adjusted size, urged by pressure of the rower's foot. A wide strap (11) which extends over the instep of the shoe is secured on the outside flank by fabric-fastening (15). The strap (11) covers any gap between heel- and toe-sections (4, 9), and a flap (16) of the heel-section (4) extends under this with its free end towards the inside flank of the shoe to assist along with the strap (11) in lifting the heel-section (4) with the rower's heel during rowing.</p> |
