The Smith is a grind trick in which the rear truck and the edge of the board both touch the rail/ledge. A Smith is similar to a Feeble, with the only difference being the location of the front truck. In a Smith, the front truck remains on the same side of the rail as where the skater approached the rail.
In the Tony Hawk series, Smiths are typically performed by pressing the grind button along with down and either right or left on the d-pad. Whether right or left is used depends on the approaching direction of the skater. Because Smiths require the front truck to stay on the same side of the rail, the direction button used must be the direction from which the skater approached the rail. Therefore a "regular" skater performs a BS Smith with down+right and a FS Smith with down+left, while a "goofy" skater performs a BS Smith with down+left and a FS Smith with down+right. </p>
