Both are Asics models, but lasts differ. Gel-Kayano 31 is labeled True to Size (True to size with correct width). Gel-1130 is True to Size (True to size).
Gel-Kayano 31 is a performance stability trainer that typically fits true to size when you pick the right width. Prefer ASICS width options over guessing with length. Lifestyle Kayano 14 sizing is a different conversation.
Gel-1130 is widely reported true to size and relatively accommodating in the toebox for a retro runner. Half up is mainly for very wide feet or thick socks — not a default. Do not assume the old “ASICS runs narrow” rule here.
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.
