FAQ

How do I convert Thursday Boot Co. shoe size to New Balance?
Match by foot length in centimeters on each brand’s chart. Example: Thursday Boot Co. US 10 ≈ New Balance US 10.0 (about 27.2 cm). Then adjust for the specific model’s fit (runs big/small/narrow).
Is a Thursday Boot Co. US 10 the same as a New Balance US 10?
Not always. Labels can map to slightly different foot lengths. Use the cm column, then check model guides on both brands.
Which direction should I read first?
Start from the brand you already wear, then open the model fit pages linked below — lasts differ even when charts match.

Clothes sizing uses a separate compare path.
