I didn't buy these on Amazon, I bought them at a SAS store.  I have been wearing this style for years and have multiple pairs in my closet. Until recently I would wear them onto the airplane when traveling. Sooo comfy!  I discovered when I have TSA precheck and am not required to take off my shoes, I still have to take these off because the buckles set off the alarm. DRAT!!  So now these go in my checked bag and I'm back to wearing loafers onto the plane.  I so miss these on the plane!
