An in-line skate (10) has an upper shoe portion (40) for receiving a person's foot that is secured to an upper surface of an upper base (56). A lower base (14) has an upper surface (64) that is detachably secured by fasteners (72) to the lower surface (60) of the upper base. A frame (16) for mounting a plurality of wheels (20) is secured to the lower surface of the lower base. The lower base defines a plurality of grind apertures (82) laterally and medially adjacent either side of the frame. A plurality of wear pads (32, 36, 38) are received on the upper surface of the lower base, and include wear portions that project downwardly through the apertures below the lower surface of the lower base. A flange defined on each of the wear pads is captured between the lower base and the upper base when the bases are assembled together. An additional wear pad (34) is secured to the exterior of the base by a tongue and groove engagement. The wear pads provide wear-resistant, low friction surfaces on the underside of the base on which a skater may slide or "grind" along elongate surfaces such as curbs, ramps, and rails. The wear pads may be replaced when worn to prolong the life of the skate.
