Captain sizing: men size down half from sneakers

Fit depth guide

Thursday Boot Co. Captain is often reported as sizing large relative to sneakers, with many wearers going down about a half size — sometimes more depending on foot volume — after accounting for leather pack-out. These are dress/casual boots with a structured last; sneaker TTS frequently leaves excess length.

Width and instep vary by leather and last iteration; read the specific product notes. Stiff leather means day-one tightness can be normal if length is correct.

Break-in is meaningful: expect several wears for the shaft and vamp to soften. Sizing up to avoid break-in usually backfires once leather yields.

Versus Docs: Docs also often size down, but lasts differ — do not assume identical UK/US mapping. Versus Red Wing: different measuring culture; get a Brannock if possible.

Sizing tips: use Thursday’s size chart and customer fit notes for the Captain specifically. Between sizes with average volume, the smaller size is the usual experiment. Thick socks may keep you closer to TTS. Prefer easy-return retailers for first Thursday boots.

Chart cm at US 9 versus the −0.5 sneaker offset

The Thursday chart on this page lists 26.3 cm at US men's 9. That is a brand foot-length ladder, not a lab internal cut — this page already says dress-boot lasts still vary by width letter. The converter offset is −0.5 US: men start a half size down from sneaker size. If your measured foot is already on 26.3 cm, that label is the chart match; the half-down is because Captain often feels long/sloppy when ordered like a trainer.

Width is a letter, not extra length. D is standard; EE/EEE exists on many leathers and is the better move if you are wide. Sizing up long to buy volume is how a boot that already runs big becomes sloppy after the short leather break-in (a few wears). Between sizes with average volume, the smaller size is the experiment this page recommends.

Compared with Doc Martens 1460, both often feel long versus sneakers, but the lasts are not interchangeable — confirm gender last before copying a Docs UK/US map onto Captain. Women's Captains on this site follow different advice (often TTS or half up). Thick socks may keep you closer to true to size; they are not a reason to skip the men's half-down if you wear thin socks.
