How does the GTS 24 fit compared with the GTS 23?

The GTS 24 should fit similarly to the GTS 23, since it’s the next version of the same stability daily trainer line. In practical terms, that usually means:

• Same general feel: secure, supportive, built for everyday road running and walking.
• Likely similar sizing: many runners can wear the same size across versions.
• Fit can still change a bit: small updates in the upper, heel, or midfoot can make one version feel roomier or snugger.

What to expect when comparing fit

• If the GTS 23 fit you well, the GTS 24 is a reasonable first try in the same size.
• If the GTS 23 felt tight in the forefoot or midfoot, check whether the GTS 24 has a more forgiving upper or if you should try a wide option.
• If you liked the support but not the exact feel, the newer model may feel a little different underfoot even if the size is the same.

Best practical advice

• Start with your normal Brooks size.
• If you’re between sizes, compare both if possible.
• If you need extra room, look for wide widths rather than sizing up too much.
• Buy from a retailer with easy returns if you can, because small version-to-version fit changes matter more than the label suggests.
