Both are Vans models, but lasts differ. Authentic is labeled True to Size (True to size; half up if wide). Old Skool is True to Size (True to size; half up if wide).
Authentic tracks the same length as other classic Vans for most people — TTS with a slim, low-volume feel. Wide feet may need half up. Minimal padding means a snug fit is normal out of the box.
Vans and most fit guides call Old Skool true to size in length with a skate-oriented snug last. Wide feet often go half up or seek wide Customs. A few retailers disagree, so try on when possible.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.
