Sentence three is the correct sentence. All of the others have some grammatical error in them. In the first, "felled" is incorrect and not a word. It also says "walk boots" instead of the correct verbal adjective "walking boots." In the second, "weren't" is not usually considered very academic and "tight" should be in the adverb form "tightly."
