Shod with sandals - The sandal seems to have been similar to the Roman solea, which covered only the sole of the foot, and was fastened about the foot and ankle with straps. The sandal was originally a part of the woman's dress; ancient authors represent them as worn only by women. In Matthew 10:10, the disciples are commanded to take no shoes, ὑποδηματα, which word is nearly of the same import with σανδαλια, sandals; but, as our Lord intimates to them that they should be free from all useless incumbrances, that they might fulfill his orders with the utmost diligence and despatch, so we may suppose that the sandal was a lighter kind of wear than the shoe: and indeed the word sandal, which is mere Chaldee, סנדל might be properly translated a light shoe; as it is compounded of סין sin, a shoe, (see Targum, Deuteronomy 25:9, Deuteronomy 25:10), and דל dal, thin, slender, or mean, as being made, not only lighter than the hypodema or shoe, but (probably) also of meaner materials. See many excellent observations on this subject in Martinius's Etymolog. Lexicon, under the word Sandalium.

But [be] shod with (e) sandals; and not put on (f) two coats.
(e) The word properly signifies women's shoes.
(f) That is they should take no change of garments with them, so that they might be lighter for this journey and travel more quickly.

But be shod with sandals,.... Which were different from shoes, and more fit to travel with, and therefore allowed when shoes were forbidden; See Gill on Matthew 10:10, though some think there was no difference between shoes and sandals, and that Christ, in Matthew 10:10, does not forbid the taking of shoes, but two pair of shoes; as not two coats, nor two staves, but one of a sort only. And
not put on two coats; that is, at a time; an inner and an outward one, or one at one time, and another at another: they were forbid change of raiment; the reasons for it See Gill on Matthew 10:10. From all which it appears, that as a minister of the Gospel ought not to be a worldly minded man, that minds earth and earthly things, and seeks to amass wealth and riches to himself, and preaches for filthy lucre's sake; nor to be a sensual and voluptuous man, serving his own belly, and not the Lord Jesus Christ, feeding himself, and not the flock; so neither should he be filled with worldly cares, overwhelmed in worldly business, and entangled with the affairs of this life: he ought to have his mind free from all solicitude and anxious concern, about a subsistence for himself and his, that so he may with greater and more close application attend to his ministry, to preparations for it, and the performance of it; and give up himself entirely to the word and prayer, and not have his mind distracted with other things: upon which account it is highly necessary, that the people to whom he ministers should take care, that a sufficient provision be made for him; that he may live without any anxious care and thought about such things, and his mind be more intent about the work he is called unto: and which is what our Lord chiefly designs by all this, who has ordained that they that preach the Gospel, should be comfortably provided for, and live of it; and which, as it makes for the peace of their minds that minister, it issues in the advantage of those who are ministered to.

Be shod with sandals. Matthew forbids shoes, instead of which they were to wear sandals. The ancient shoe resembled the modern; the sandal was a sole tied on the foot. The latter was usually worn by the common people and they were to dress like them.

Be shod with sandals - As you usually are. Sandals were pieces of strong leather or wood, tied under the sole of the foot by thongs, something resembling modern clogs. The shoes which they are in St. Matthew forbidden to take, were a kind of short boots, reaching a little above the mid - leg, which were then commonly used in journeys. Our Lord intended by this mission to initiate them into their apostolic work. And it was doubtless an encouragement to them all their life after, to recollect the care which God took of them, when they had left all they had, and went out quite unfurnished for such an expedition. In this view our Lord himself leads them to consider it, Luke 22:35 When I sent you forth without purse or scrip, lacked ye any thing?
