Yeezy Slide Onyx: Size Guide, Fit & Review
The Yeezy Slide Onyx runs snug and narrow: owners with slim feet go true to size, most others go one size up (whole sizes only). The non-obvious detail from Reddit: fit can vary by factory. An owner who has both colorways reports his China-made Onyx pairs fit a bit snugger than his India-made Dark Onyx pairs in the same size, so even two pairs of the same size can feel different. Below you’ll find owner reviews, a sizing guide, a FAQ and where to buy.
Yeezy Slide Onyx Review
Here is what owners are saying:
“The Onyxs fit a bit snugger than the Dark Onyxs but I went TTS for both and am happy with how both fit.” (r/yeezys)
“Forgive me for wanting some sizing consistency in my expensive slides and sneakers” (r/yeezys)
Thank you u/Kicka14 and u/borklazer2 for the on-feet photos shared on Reddit.
Yeezy Slide Onyx Sizing Guide
Should you size up?
- Slim or narrow feet: true to size gives a snug, secure fit.
- Average to wide feet, or between sizes: go one full size up. Yeezy Slides only come in whole sizes.
Factory variance
Owners on Reddit report that pairs made in China tend to fit a touch snugger than pairs made in India in the same marked size. If your pair feels off compared to a previous one, check the origin on the size tag before assuming it is fake.
Legit Check: How to Spot a Fake Yeezy Slide Onyx?
These checks are crowd-sourced from a Reddit legit check thread. They are individual redditors’ opinions, not an official authentication method, so treat them as first clues rather than proof.
- Check the box label first: Onyx and Dark Onyx are two different colorways, and a mismatched pair sold as Onyx was spotted that way. (r/yeezys)
- Look for the stickers that come with retail Slides and Foam Runners: a buyer flagged his suspect pair because the box had none. (r/yeezys)
- Do not judge on shade alone: an owner with three adidas-direct Onyx pairs from three drops reports all three are slightly different shades due to factory and QC variance. A darker or lighter pair is not automatically fake. (r/yeezys)
Yeezy Slide Onyx FAQ (based on owners’ reviews)
Does the Yeezy Slide Onyx run small?
Yes. The consensus among Reddit owners is snug and narrow. Slim feet can go true to size, most others go one size up.
Why do two pairs in the same size fit differently?
Owners point to factory variance: China-made and India-made pairs of the same marked size do not feel identical. One owner found his Onyx (China) a bit snugger than his Dark Onyx (India) at the same size.
Onyx or Dark Onyx: is the fit the same?
Per an owner who has both, the fit is close and true to size worked for both, with the Onyx feeling slightly snugger. The Dark Onyx is a deeper black; the Onyx is a dark graphite grey.
Where can you buy the Yeezy Slide Onyx?
adidas no longer sells them, so the resale market is where owners buy today. You can check current listings and prices on eBay right here.
