A system comprising a pair of ladder support apparatuses 10 for a pair of footings of a ladder, wherein each apparatus comprises a base member (12, fig 2) providing a ground contacting surface (16, fig 3) and a ladder contacting surface 24. On an upper side of the base member is provided an abutment member 28 against which a footing of the ladder can abut. The apparatus may receive a stabilizer bar attached to the ladder, and may comprise a grouping of spikes (20, fig 5) or an elastomeric mat on the ground contacting surface and ladder contacting surface. The apparatus may comprise a handle 14 formed in the base member, and the base may be flexible for use on uneven ground. Preferably the apparatus is made from a plastic, polypropylene material.
