Both are Vans models, but lasts differ. Classic Slip-On is labeled True to Size (True to size (match Authentic if you own one); half up for wide feet; half down only if you want extra snug and accept stretch). Old Skool is True to Size (True to size; half up if wide).
Do Vans Classic Slip-Ons run big or small? Large owner databases land on true to size — often the same number as Vans Authentic. Canvas stretches, so a slightly snug start is normal; wide feet often half up because there are no laces for width lockdown. Some guides still say half down to prevent heel slip after stretch — that is preference, not the modal TTS report. Confidence is medium: TTS is the strong center, with half-up/down split by width and stretch tolerance.
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.
