'Sandals' in the Bible

I have led you in the wilderness forty years; your clothes have not worn out on you, and your sandals have not worn out on your feet.

Now you also know what Joab the son of Zeruiah [my sister] did to me, and what he did to the two commanders of the armies of Israel, to Abner the son of Ner and to Amasa the son of Jether, [both of] whom he murdered; avenging the blood of war in [a time of] peace. And he put the [innocent] blood of war [of Abner and Amasa] on his belt that was around his waist, and on his sandals on his feet.

(The Bridegroom)“Why should you gaze at the Shulammite,As at the dance of the two armies?“How beautiful are your feet in sandals,O prince’s daughter!The curves of your hips are like jewels,The work of the hands of an artist.

Thus says the Lord,“For three transgressions of Israel and for four (multiplied delinquencies)I will not reverse its punishment or revoke My word concerning it,Because they sell the righteous and innocent for silverAnd the needy for the price of a pair of sandals.

So that we may buy the poor [as slaves] for silver [since they are unable to support themselves]And the needy for a pair of sandals,And that we may sell the leftovers of the wheat [as if it were a good grade of grain]?”
