Both the Nike Pegasus 40 and Zoom Fly 5 are true to size.

From my fitting experience, the Pegasus 40 maintains a true-to-size fit, hugging the foot comfortably with ample space in the toe box. Also, Pegasus 40 offers regular and broader widths on the website.

Therefore, if you have a wider foot, you can easily grab the true size with a wider width.

I find that a good choice cause it’s a performance shoe, and I need it to fit comparatively tight when I need to push my pace.

However, Zoom Fly 5 doesn’t offer wider choices, so if you have a more comprehensive fit, sizing up half is necessary.

Also, its snug fit, especially around the midfoot, contributes to stability during faster-paced runs but requires attention to sizing nuances.
