The shoes of peace is using the gospel to walk with God. The gospel is a part of your spiritual armor. You have peace when you are prepared for battle. You prepare for battle by knowing God's Word. Your foot ware determines how quickly and steadily you can move. The same is true with how well you know God's Word. If you are in God's Word every day, then you can be prepared, stable, and at peace when Satan attacks.
Your foot ware is what gives you the ability to be a warrior, athlete, civilian, or worker. When the armor of God was describes and written by Paul the shoes were boot like sandals that covered their lower legs and feet. On the bottom they had little spikes. The shoes provided protection, but breathes. They kept the men sturdy when they fought, but also the ability to run without getting hurt or slipping. Knowing you are sure footed gives you peace when you are being attacked from all sides.
Satan wants to destroy your peace, so he will come after your concentration when you are reading God's Word, distract prayer, or put obstacles in your way where you don't pray or get in God's Word. He plays dirty. If he can distract you from spending time with God, then he can cause discord, division, disruption, disturbances, and other things that will steal your peace. If you have chaos or confusion in your life, then know that is from Satan. That is what you need to fight.
Where you lack peace you know Satan is at work. This is where you need to tighten your shoes and turn to God to fight with or for you. Peace in your personal and spiritual life leads to healthy relationships, better health, and a mind that is clear. Peace opposes bitterness, resentment, and defensiveness. Peace works with forgiveness, love, and harmony. All of these are good for relationships.
Satan attacks your minds, heart, body, relationships, and even your soul. God has provided the way to protect all of these. The truth and righteousness cover you with protection, but he gospel gives you the ability to use it. Peace gives you emotional stability to sleep well, seek healthy living, and pursue God. There is no room for dysfunction when you cling to God's peace. Your soul finds it's stability in the Gospel. It makes your ready to proclaim the truth and live out righteousness.
