ABSTRACT:
A stilt assembly with interchangeable sections for varying the height thereof. A base assembly, middle assembly and foot support assembly include puzzle registries which allow for the stilt to be assembled with two assemblies (base and foot support assemblies only) for a shorter configuration, or with three assemblies (base, middle, and foot support assemblies) for a taller configuration. A foam spacer block provides height spacing in at least one assembly, and provide shock absorption and fail-safe height support, without failure-prone mechanical mechanisms.
