A shoe (10) for a crawler track has two roller paths (16, 17) thereon, upon which a dual rim roller travels in use. The roller paths (16, 17) are aligned with leading and trailing lugs (11, 12) respectively, of the shoe 10. Drive lugs (18, 19) are provided on the outside of the roller paths (16, 17). In use, the drive lugs (18, 19) are engaged by sprocket teeth to drive the crawler track. The drive lugs (18, 19) stand proud of the roller paths (16, 17), but may also be recessed below the roller paths. |
