A support brace includes a bottom section that has planar top and bottom surfaces. The bottom surface is seated on a ground surface, and the top surface abuts a bottom surface of a user foot. The bottom section has linear sides wherein one is diagonally offset from adjacent ones. A first wall extends upwardly from the bottom section. A second wall extends upwardly from the bottom section and has a longitudinal length registered perpendicularly to the first wall. The second wall has sloping top surfaces extending upwardly and away from the first wall that define a shoulder against which a wood plank is supported. A third wall abuts the bottom section and is spaced from the second wall for defining a passageway therebetween. The second wall has a lowest elevation defined above a highest elevation of the third wall.
