Abstract: A leg attachment assembly for a stilt device of the type used to support a user above a base surface. The leg attachment assembly has a curvilinearly extending leg band configured to partially surround an upper leg portion of a user's leg. The leg band is attached to a distal end of a support pole using a pair of spacers and associated fasteners. One or more strengthening ribs extend in a lateral direction between contact locations of the spacers. The strengthening ribs extend beyond the spacers to enhance rigidity of the leg band during use. A securement strap can be used to encircle the user's leg and the leg band to attach the stilt to the leg. The strap can be routed between the spacers and over the top surfaces of the strengthening ribs so that, when the strap is tensioned, the ribs prevent slippage or displacement of the strap.
