New Balance fit — the short version
True to size across the road line — your Asics number carries straight over. The 1080 comes in narrow, standard, 2E and 4E widths; broad forefeet do better in a 2E than a half size up. The Rebel runs roomier in the forefoot, and the SC Elite fits snug through the midfoot, which is normal for a race shoe.
