Adidas Size Guide
2 min read · Updated October 27, 2026
adidas fit depends on the model and preference. Samba generally fits true to size; a blanket half-size reduction is not reliable.
Samba guidance
adidas describes Samba as generally true to size. Its guide suggests considering half a size up for wider feet. Check the particular Samba version and preferred fit rather than automatically choosing a smaller pair.
Ultraboost needs version-specific advice
The official Ultraboost guide discusses different fit preferences and versions. A single adjustment for every performance and lifestyle model is not supported. Compare the current chart and product guidance.
EU fractional labels
adidas footwear charts commonly use EU one-third and two-third values. Do not replace those with a fabricated sequence of half sizes. US, UK and JP rows should be read from the same chart.
Match measured heel-to-toe length
A JP label row and a measured heel-to-toe row can show different values. Choose from the measured-foot guidance, then verify width and hold with the intended socks.
