Onitsuka Tiger California 78 EX Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Nike Air Force 1

The Air Force 1 is built on a high-volume, wide last that notoriously runs large. Because the California 78 EX uses a much narrower profile and shorter relative length, you must size up by a half-size to compensate for the reduction in internal volume and prevent midfoot constriction.

Adidas Samba

Both models utilize a slim, retro-inspired narrow last, making for a direct size translation. However, the California 78 EX offers slightly more vertical room in the toe box and superior underfoot cushioning, meaning those who find the Samba's width acceptable will enjoy a more forgiving fit in the same size.

Nike Dunk Low

Nike Dunks offer a wider, more rounded toe box compared to the streamlined and tapered front of the Onitsuka. To avoid toe jamming during the foot's natural expansion, a half-size increase is recommended when moving from the roomier Dunk silhouette.

New Balance 574

New Balance is the industry standard for wide, high-volume lasts. The California 78 EX is significantly leaner; if you occupy the full width of a standard New Balance, you will likely need to size up a full increment to avoid 'muffin-topping' over the narrow Onitsuka midsole.
