IIRC most futurists do not think all things have been put under Christ’s feet yet; preterists think all things were put under Christ’s feet in AD 70. But Paul’s statement in Ephesians suggests both are wrong.
Ephesians 1:22 (ESV)
20 that he worked in Christ when he raised him from the dead and seated him at his right hand in the heavenly places, 21 far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the one to come. 22 And he put all things under his feet and gave him as head over all things to the church, 23 which is his body, the fullness of him who fills all in all.
