Nike Blazer Mid '77
Sizing & fit guide

Our verdict
True to size
The Nike Blazer Mid '77 fits true to size but runs narrow and a touch short — most wearers take their normal Nike size. Narrow feet can go down a half; if your toes hit the front or you have wide feet, size up a half. It sits about ½ size up from Converse Chuck Taylors.

Why the Nike Blazer Mid '77 fits this way

The Nike Blazer Mid '77 has a true-to-size consensus with two consistent caveats: it runs narrow, and it's slightly shorter than other Nike retros. Wearers confirm the baseline plainly — "They're TTS" and "pretty true to size" — while flagging the shape: "Blazers are narrow and a tiny bit shorter than an AJ1. If the 11 was tight on the AJ1, I'd def go up." Another reports being "10.5 AJ1, got a 10.5 Blazer" — same number as the Jordan 1, confirming TTS against that anchor.

The most useful cross-brand reference is Converse: "I'm consistently .5 bigger than Converse. I wear 11 Converse and 11.5 Blazers and they fit the exact same." Since Converse run large, the Blazer sitting a half size up from your Chuck size lands you back at your true Nike number.

Because the Blazer is narrow and slightly short, the fit splits at the edges: narrow feet can size down a half ("if you have a narrow foot, going down half a size wouldn't hurt"), while wide feet or anyone whose toes brush the front should go up a half. Net: true to size for standard feet; ½ down for narrow feet, ½ up if the toe box feels short or you have wide feet. The vulcanized-style sole and leather upper give a little with wear.

Common scenarios

I wear US 10.5 in Air Jordan 1. What size Blazer Mid '77?

US 10.5 — the Blazer fits true to size against the AJ1. If the AJ1 was already tight for you, size up a half since the Blazer is narrower and a touch shorter.

I wear US 11 in Converse Chuck Taylors. What size Blazer?

About US 11.5 — Converse run large, and the Blazer sits a half size up from your Chuck size, which lands at your true Nike number.

I have narrow feet. Should I size down?

Yes — narrow feet can go down a half in the Blazer without issue. Standard feet stay true to size; wide feet or short-toe-box discomfort go up a half.
