Yeezy Slides sizing: size up one, TTS if narrow barefoot

Fit depth guide

Slides are molded EVA with no half sizes on most runs. That alone pushes half-size sneaker wearers to the next whole size up.

Conditional camps: (A) Average/wide + socks → +1 full size (sometimes +2 on older tight colorways). (B) Narrow barefoot indoor use → TTS can work if toes and heel stay on the footbed. (C) Half-size wearer → always round up to the next whole size.

Foam molds a little over days, but not enough to fix a strap that bites the midfoot. Day-one snugness under the strap is expected; numbness is not.

Batch variance (OG Enflame/Core vs later Bone/Onyx-era) is the main reason this stays medium: treat +1 as the safe default and TTS as the exception you confirm with returns.

Same Yeezy cm ladder as 350 V2, different offset

The Yeezy chart on this page lists 26.1 cm at US men's 9 — the same foot-length ladder as Boost 350 V2. That number is label matching, not a molded-EVA fit proxy. The converter offset here is +1 US, not the 350's +0.5. Do not copy 350 V2 half-up onto Slides: this last is whole sizes, a narrow midfoot band, and a default +1 from usual sneaker size.

If you wear US 9 sneakers, the chart's 26.1 cm is the US 9 row; the starting Slide is still 10 for most people. Half-size sneaker wearers (9.5) have no 9.5 Slide on most runs — round up to the next whole size, which is already the +1 default if you think in 9.5→10.5 terms only after you pick a camp. Narrow barefoot indoor use is the TTS exception; wide feet and sock wearers are +1 to +2. Firm foam molds over days; it will not rescue a strap that is a full size short.

Confidence stays Partial because newer colorways can feel slightly roomier than early drops. Treat +1 as the safe default and TTS as the exception you confirm with returns. Related model on this site: 350 V2 still uses half sizes and a Primeknit offset — convert separately.
