Samba OG

Samba OG sizing: true to size length, narrow last

Samba OG is true to size in length and runs narrow. Stay TTS if your feet are average. Half up mainly for width, not extra length — a longer Samba can still pinch. Leather needs a short break-in.

Fit scenarios

Narrow or average feet
True to size. Let the leather vamp give over a few wears rather than sizing up into heel slip.
Wide feet
Half up adds length more than width. You can still pinch at the T-toe. Many wide-footed shoppers move to Gazelle or Spezial instead of forcing Samba.
Coming from Gazelle
If Gazelle is US 9.5, Samba is often US 10. Gazelle’s half-down is a length correction; Samba’s issue is the skinny last.
Between sizes
Stay TTS if width is average. Lace the top eyelets. Do not add a half size “for break-in” on a last that is already long enough.
Width
Narrow low-volume last — common complaint
Break-in
Leather needs short break-in

Summary

Adidas positions Samba as true to size with a regular-but-narrow fit; RunRepeat and wearer reports agree length is TTS while the toebox pinches wider feet. Stick to your usual size if narrow/average; go half up primarily for width, not length.

Fit depth guide

Samba OG sits on a flat indoor-soccer last. Length is usually fine at your Adidas size. The famous complaint is a skinny midfoot and T-toe, which is why “does Samba run small?” threads usually mean width, not a short labeled size.

Why 27.3 cm still pinches: the 66.1 mm toebox

The lab cut at US men's 9 on this page is 27.3 cm internal (273 mm), 91.2 mm forefoot, and 66.1 mm toebox. Length is not the problem: 27.3 cm is a normal sneaker cavity. The 66.1 mm toebox is the pinch. That is why the fit bar stays true to size for length while the verdict is Runs Narrow, and why the converter offset is +0 US.

Half up for width adds length more than it opens the T-toe. Average and narrow feet should stay true to size and let the leather vamp give. Wide feet should try on or move to a roomier terrace sibling rather than stacking half-up on a last that is still skinny.

Samba is typically the narrowest of Samba / Gazelle / Spezial. Lace the top eyelets for lockdown if you stay TTS. Nike Dunk or AJ1 US 10 is not automatically Adidas US 10 — convert by last, not by the number on the box.

FAQ

Does the Adidas Samba OG run big or small?
True to size in length, narrow in the last. The 66.1 mm lab toebox at US 9 is the pinch people call “runs small.” Average feet stay TTS; wide feet half up or pick Gazelle / Spezial.
What size should I buy in the Adidas Samba OG?
Your usual Adidas size if width is average. Half up mainly for width, not extra length. A longer Samba can still squeeze the T-toe.
What if I am between sizes in the Adidas Samba OG?
Stay TTS if you are not wide. Lace the top eyelets and let leather give. Sizing up for break-in often adds heel slip without opening the toebox.
Do the Adidas Samba OG work for wide feet?
Poorly, for many people. Half up is a length patch on a skinny last. Gazelle or Handball Spezial is usually the better terrace option.
Should I size up in the Adidas Samba OG for thick socks or break-in?
Leather needs a short break-in, not a size jump. Try the sock you will wear. Thick socks plus half-up can leave a long, still-narrow shoe.
