An adapter for use with a walker is disclosed. The adapter has a mesh that includes a running surface for engaging soft surfaces such as sand, dirt, and the like, into which conventional walker legs generally sink. A post on the adapter is configured to lockingly engage an end portion of one of the walker legs. Optionally, each adapter has two posts that are separated from each other by a distance that is substantially equal to a distance between end portions of two legs of a walker. In use, the adapter is positioned lateral to a users feet, substantially outside of the space defined by a walker handrail, to avoid the user stepping on or tripping over the adapter.
