A walking aid support assembly stably supports a leg of a user while using a crutch. The assembly includes a pair of mounting members each having a first flange and a second flange. Each of the second flanges is configured for coupling to a crutch frame. A support member is coupled to each of the first flanges. The support member is configured to support a leg of a user above a ground surface. Each of a pair of braces is coupled to and extends between the support member and an associated one of the mounting members. Each brace has a bottom portion and an upper portion. The bottom portion of each brace is coupled to the first flange of the associated mounting member below the support member. The upper portion of each brace is coupled to a front section of the support member positioned distally relative to the mounting members.
