Ladder legs and adjustable leg extension ladder levelers
Improvements to the leg extension of an adjustable ladder leveler and, more generally, improvements to ladder legs. A shoe with fastener holes to reduce leg slippage. A shoe with a claw that folds to be parallel to the ladder leg and then slides upward with respect to the leg thereby becoming locked into position so that it cannot move away from being parallel so long as weight is applied on the ladder. Increased length and modified shape on the distal ends of control levers on the extendable leg ladder leveler so that the levers can be operated with a foot and do not require hand operation.
