Brooks Ariel GTS 24 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Brooks Adrenaline GTS 24 (Women's)

The Adrenaline GTS 24 is a lighter, slimmer daily trainer. While both models feature a lower-volume toe box for this edition, the Ariel GTS 24 incorporates a significantly wider, stiffer base platform and rigid upper overlays. Transitioning to a half-size larger in length or opting for a wider width prevents lateral toe friction and accommodates the low-clearance vertical space of the Ariel's upper.

Brooks Beast GTS 24 (Men's)

The Beast GTS 24 is the direct men's counterpart to the Ariel GTS 24. For female runners requiring an exceptionally wide fit, converting to the men's model is an excellent sizing strategy. To match length properly, the size must be increased by 1.5 sizes on the women's scale, and a men's Medium (D) width corresponds directly to a women's Wide (D) for an identical volumetric match.

Hoka Gaviota 6 (Women's)

Hoka's Gaviota 6 runs true to size but is built with a significantly wider, higher-volume toe box and a lower 6mm heel drop. In contrast, the Ariel GTS 24 features a narrower, lower-volume upper and a steep 12mm drop. Sizing up a half-size in the Ariel is necessary to compensate for the tighter vertical clearance and match the overall forefoot room of the Gaviota.

ASICS Gel-Kayano 32 (Women's)

The ASICS Gel-Kayano 32 features a premium, plush, high-stack design with a slightly straighter and roomier toe box than traditional ASICS models. Because ASICS running models generally trend slightly narrow, a direct true-to-size match provides a comparable balance of length and width when transitioning into the Ariel GTS 24.
