A foot grille comprises a multiplicity of elongated plank members (14-1; 14-2; 14-3; 14-4; 114), each being of substantially uniform cross-section along its length and including a substantially planar base portion (16; 116) having parallel side edges (18, 20; --, --) and at least one supporting leg portion (22; 122) depending from the base portion, extending longitudinally substantially coextensively with the base portion, and being adapted to support the base portion in spaced relation above a supporting surface. Tread members (12-1; 12-2; 12-3; 12- 4; --) are attached to the upper surface of each plank member. A snap-fit coupling (26; 126) joins each adjacent pair of plank members along a juncture between their adjacent side edges. Each snap-fit coupling includes first and second arm portions (28, 30; 128, 130) on one of the adjacent plank members that are resiliently deformable relative to each other and a third arm portion (32, 132) on the other of the adjacent plank members that is received between the first and second arm portions of said one plank member. The first and third arm portions have a first inter-engaging tongue and groove pair (34,134; 36,136), and the second and third arm portions have a second inter-engaging tongue and groove pair (38, 40; 138, 140).
