Brooks Running Shoe Sizing Guide
Brooks is one of the most consistent brands for sizing — but there are still important differences between models. Here's what you need to know, plus community reports from real runners.
Do Brooks Run True to Size?
Brooks generally runs true to size, making it one of the more predictable brands when switching from another shoe. The Ghost is the gold standard — it's the most-reported reference shoe in the RunSized database precisely because it fits so consistently.
That said, there are exceptions. The Glycerin runs slightly long for some runners. The Hyperion performance line runs shorter and narrower than the training line. Don't assume what works in the Ghost will carry directly to the Hyperion.
Width note: Brooks is one of the best brands for width options. The Ghost, Glycerin, and Adrenaline GTS all come in narrow (B), standard (D), and wide (2E) for men. If you have wide feet, Brooks is often the easiest brand to fit without compromising on length.

Brooks vs Other Brands Sizing
Both tend to run true to size in length. Brooks has a slightly roomier toebox and more width options than most Hoka models. If you find Hoka too narrow, Brooks Ghost or Adrenaline GTS may be a better fit.
Brooks training shoes run more consistently than Nike's range. Nike Pegasus is comparable to the Ghost in length. Nike racing shoes (Vaporfly, Alphafly) run significantly shorter than anything in the Brooks line.
Both run true to size for most models. ASICS Gel-Nimbus and Brooks Ghost are comparable in length and width. ASICS tends to run slightly narrower in the toebox across their range.
Both brands are reliable for fit consistency. New Balance offers a wider range of width options (B through 4E) versus Brooks (B, D, 2E). For extreme wide or narrow feet, NB has more options.
Tips for Sizing Brooks
- Ghost is your anchor: If you know your Ghost size, it transfers reliably to the Adrenaline GTS and Launch. Use it as your reference point.
- Glycerin runs long: If switching from Ghost to Glycerin, try half a size down first. The Glycerin's roomier last can make it feel longer than expected.
- Hyperion line runs short: Brooks performance shoes use a different, more snug last than the training line. Go half a size up from your Ghost size for Hyperion GTS or Hyperion Max.
- Width first: Before sizing up in length to accommodate width, check if your target shoe comes in wide. Brooks is one of the best brands for this.
