Every Saucony conversion below is verified against the brand's official size chart.
Saucony fit — the short version
True to size, in line with your Asics number across the core range. The Ride and Triumph pair a snug midfoot with a moderate toebox; the Endorphin race shoes taper harder up front, so wide feet go half a size up in the Speed and Pro, or take a wide width in the daily trainers.

Common questions
Does Saucony run true to size? Yes — true to size, in line with your ASICS number across the core range.
Should wide feet size up in the Saucony Endorphin? The Endorphin race shoes taper harder up front, so wide feet go half a size up in the Speed and Pro, or take a wide width in the daily trainers.
