Both are Yeezy models, but lasts differ. Boost 350 V2 is labeled Runs Small (Size up half a size (full size if wide feet or thick socks)). Slides is Runs Small (Size up one full size (whole sizes only; between sizes always round up)).
Does the Yeezy Boost 350 V2 run big or small? It runs small — retailer guides and owner consensus converge on a half size up from everyday sneakers. Wide feet and thick socks often need a full size because the Primeknit toebox tapers and only gives a little. Do not copy V1 true-to-size advice onto V2.
Yeezy Slides typically run small and only come in whole sizes, so most wearers go up a full size from their sneaker size. Narrow feet can sometimes stay closer to TTS; wide feet and sock wearers should size up. Later production batches feel slightly roomier than early drops, so treat advice as a strong starting point rather than absolute.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.
| Boost 350 V2 | Slides | |
|---|---|---|
| Verdict | Runs Small | Runs Small |
| Advice | Size up half a size (full size if wide feet or thick socks) | Size up one full size (whole sizes only; between sizes always round up) |
| Width | Tapered Primeknit toebox — limited stretch; thick socks often force full size up | Narrow midfoot band; foam molds after break-in |
| Break-in | Primeknit gives slightly but will not fix a short size | Firm foam softens and molds over days |
| Fit offset | +0.5 | +1 |
| Confidence | high | medium |
