ASICS
True to SizeASICS fits true to size but with a slightly narrow forefoot in standard widths. Most runners and trainers wear your normal size, though wide-footed shoppers should look for 2E or 4E variants in Gel-Kayano, Gel-Nimbus, and GT-2000. The Gel-Lyte and lifestyle lines fit similarly to the runners. There is no need to size up unless you are wearing thick orthotics.
ASICS is generally true to size. Order your usual size.
Slightly narrow, wide versions available
