Brooks Hyperion Max 3 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

ASICS Superblast 2

The ASICS Superblast 2 provides a significantly more spacious, high-volume toe box and a more accommodating, stretchy upper material. If you have a narrow foot and wear a US 10 in the Superblast 2, you can buy your true length size (US 10) in the Brooks Hyperion Max 3. However, if your feet are average-to-wide and you rely on the natural roominess of the ASICS toe box, you must size up a half-size to US 10.5 in the Hyperion Max 3 to compensate for its rigid, non-stretchy jacquard mesh and lower vertical clearance.

New Balance FuelCell SC Trainer v3

While standard US length sizing matches up identically, New Balance and Brooks utilize slightly offset UK/EU conversion scales. The SC Trainer v3 features a highly flexible and forgiving upper construction. If you normally wear a US 10 in New Balance but have a wider foot profile, understand that the Hyperion Max 3 lacks an available wide option and has a highly restrictive upper. To accommodate this structural discrepancy, wide-footed runners should size up a half-size, while true neutral, narrow-footed runners should stick to their normal length size.

Nike Zoom Fly 6

Both models run true to size lengthwise and are built on narrow, performance-driven lasts with inherently tight toe boxes. Address the compensation factor carefully here: if you already size up a half-size in the Nike Zoom Fly 6 specifically to obtain more width, you must maintain that scaled-up size in the Hyperion Max 3 because the Brooks is similarly narrow in the forefoot and features an even tighter midfoot bootie with severe dorsal lacing pressure. If the Nike fits you perfectly true-to-size in length and width, buy your standard true size in the Brooks.

adidas adizero Boston 13

Adidas running shoes typically run longer and noticeably wider than Brooks models in the same size category. Transitioning from the roomy, relaxed upper environment of the Boston 13 to the Hyperion Max 3 requires most runners to select a half-size larger to prevent extreme toe compression and cramping. Only select your true standard US size if you explicitly desire an ultra-snug, lower-volume race-like wrap and possess narrow feet.
