Gel-Kayano width availability
Available in standard (D) width only.
Only the standard (D) width is listed, so very wide or very narrow feet may need to adjust length or choose a wider brand.
Fit notes
Use the fit offset and width list together: the size label gives the baseline, while this model-specific fit data tells you what to check first.
