Summary

Vans Classic Slip-On fits true to size like Authentic/Old Skool for length. Because there are no laces, wide feet and thick-sock wearers more often go half up. Heel slip means you sized too long — the elastic gore is not a reason to size up if length is already right.

Fit depth guide

Start with the same size as your Vans Old Skool if that already fits. Without laces, you cannot micro-adjust midfoot — choose length for secure heel, not toe jam.
