Summary

574 is generally true to size in length with an accommodating SL-2 forefoot, but some owner datasets call standard D snug and prefer half up. Prefer official 2E/4E over guessing length if you already know you need wide. TTS vs half-up camps both appear — Partial.

Fit depth guide

New Balance 574 is a lifestyle classic. Length usually tracks your NB size; the debate is volume in D width.

Conditional: (1) Narrow/normal who like a little wiggle → TTS. (2) Wide or high-volume forefoot → stay TTS length and move to 2E/4E. (3) D feels short/snug even with correct width history → half up is the second experiment, not the first.

Versus 990v6 / 550 / 9060: 574 is more forgiving than 550’s narrow story and less plush than 990v6. Use width letters before inventing a new length rule.
