Modern Interpretation: Ain't much to add here — it's the one commandment you should hold true above all others. Wear your sneakers. Not saying you need to wear them home from the store (although that is a rare pleasure these days), but whether you wear them the next day or the next year, make sure you get them on your feet and on the street. If you just want to look at them in their pristine state, take a picture. It will definitely last longer.
