One pattern emerges from the sizing data: foot length in centimeters is the most reliable anchor across all regions. Here is the official Adidas conversion for core sizes relevant to Irish shoppers.

The pattern: lifestyle shoes (Samba, Gazelle, Stan Smith) track true to the official conversion. Running shoes (Ultraboost, Adizero) tend to run half a size long, so consider sizing down if you prefer a snug fit. Adidas size guide, brand authority and SIZER, size specialist both confirm this distinction.

“Measuring your foot in centimeters at the end of the day and wearing the socks you plan to use is the most reliable way to find your Adidas size.”

The implication is clear: Adidas shoes are not a one-size-fits-all proposition. The brand’s strength lies in offering distinct fits for different uses — running shoes that prioritize toe room, lifestyle sneakers that stay true to size, and heritage lines like Spezial that reward those who measure carefully. For the Irish shopper, the choice is straightforward: use the centimeter measurement, match it to the model’s fit profile, and buy from a trusted retailer. Ignore that advice, and you risk ending up with a pair that either pinches or slips.
