Abstract
A ventilated in-line skate (10) includes a lower frame portion (12) mounting a plurality of wheels (14) and an upper shoe portion (16). The upper shoe portion is secured to a base (24) that defines an upper surface (26) adapted to receive the upper shoe portion (16), and an exterior, lower surface (28) to which the lower frame portion (12) is secured. The base defines multiple ventilation channels (30) that traverse its upper surface (26) from a corresponding plurality of inlet apertures (32, 39) to an outlet aperture (34) defined within the exterior surface of the base. The upper surface of the base receives a last board (54) and insole (58), each of which includes a plurality of vertical apertures that permit airflow from the interior of the upper shoe portion to the ventilation channel. The base draws air and moisture from the interior of the upper shoe portion during use.
