So good shoes for long walks

It's amazing and very comfortable to wear and feels really comfortable and good....but it does beeps and alarm when passing through security gates at airport. It does not mention of any metal used in these shoes... but unfortunately it does beep... I'm guessing it is because of shank. And now I have to remove these shoes every single time that I pass through security , which is negative point for me.
