Does it run big or small?

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.
