Size & Fit Guidance Most runners say the fit feels secure and true to size. For the best fit, we recommend your usual size if you like a performance-minded hold, while runners who prefer extra room up front or have wider feet may prefer going up half a size. Best For Best for daily training, long runs, and tempo sessions when you want one shoe that can comfortably handle a wide range of paces. Cushioning & Road Feel Reviewers consistently highlight the balanced ride: cushioned enough for longer efforts and daily mileage, yet firm and snappy enough for uptempo work. That mix gives the Boston 13 a smooth, stable feel on the road without losing the fast, efficient character runners want from the Adizero line.
