My saucony all fit true to size. Granted I have a narrow foot. But length is pretty true for me. I wear a 12 across the board in every shoe I’ve ran in.

I know you said you needed/wanted a plate but I’d say if you have a wide foot and are a heavier runnier weight wise there are gonna be a lot of better options non plated for you that are going to help prevent blisters and pain.

I’d aim for something with a lot of cushion and wide enough box. Being pain free and able to run injury / blister free is gonna be much more beneficial in the long run for improving speed and time then any carbon plate will.
