Should I size up in the Asics Gel-1130 for thick socks or break-in?

Break-in: Minimal. Thick socks add volume — try the sock you will wear with the usual size advice before jumping a full size. See the thick socks & boot break-in guides.

Summary

ASICS Gel-1130 fits true to size for most people, with a more forgiving mesh toebox than the old “ASICS runs narrow” stereotype. Half up is mainly for very wide feet or thick socks — not a default. Do not copy Kayano 14 sizing into the 1130.

Fit depth guide

The Gel-1130 is a 2008 stability runner revived as a lifestyle shoe, and the fit is one of the easier ASICS stories. RunRepeat’s owner poll (hundreds of votes), MoreSneakers, and SizeChartGuru all call it true to size. Lab length sits near the sneaker average; width is slightly above average, which is why wide-foot owners often stay TTS instead of half-upping.

The stereotype that “ASICS runs narrow” belongs to other models (Kayano 14, some GT lines), not this one. The mesh upper has give. Half a size up is a preference for extra room or thick socks, not a correction for a short last. Narrow feet who want a locked feel can stay TTS and use lacing rather than sizing down.
