Feet signify the walk. A calf’s foot is straight, signifying that the walk of the living creatures is not crooked in human cleverness but is straight, frank, faithful, and honest in the divine grace (2 Cor. 1:12; 4:2; Matt. 5:37; 21:23-27; 1 Cor. 4:21; Gal. 2:11-14). A calf’s foot is also cloven, divided, signifying that in their walk the living creatures can discern what is right and what is wrong and what is clean and what is unclean in the eyes of God (Phil. 1:9-10; cf. note Lev. 11:31). That the feet of the living creatures sparkled like the sight of burnished bronze signifies that their walk has been tested and examined by the Lord and that it shines, giving light to others and being a test to their walk (cf. note Rev. 1:151a).
A calf signifies freshness, livingness, and vigor (cf. Psa. 29:6; Mal. 4:2). The walk of the living creatures is vigorous, full of life, freshness, and newness, like a young calf (cf. Rom. 6:4; 7:6).
