v. walked, walkÂ·ing, walks. v.intr. 1. To move over a surface by taking steps with the feet at a pace slower than a run: a baby learning to walk; a horse walking around a riding ring. 2. a. To go or travel on foot: walked to the store.
1) Walk (in this sense) is an intransitive verb. 2) The prepositional phrase is modifying the verb, but it is not receiving the action of the verb, so it should not be considered a direct object. 3) The store is an object of the preposition. 4) Sometimes, prepositions and direct objects can be confusing, I was typing up the lab report.
