Actually no it is forbidden in the Bible! It was a pagan custom to kiss the feet of emperors!
Acts 10: 25-26 (NASB)
25 When Peter entered, Cornelius met him, and fell at his feet and worshiped him. 26 But Peter raised him up, saying, “Stand up; I too am just a man.”
Rev 22: 8-9 (ESV)
8 I, John, am the one who heard and saw these things. And when I heard and saw them, I fell down to worship at the feet of the angel who showed them to me, 9 but he said to me, “You must not do that! I am a fellow servant with you and your brothers the prophets, and with those who keep the words of this book. Worship God.”
