Hoka Mach 6 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Brooks Ghost Series (Ghost 15, Ghost Max)

The Brooks Ghost series is widely celebrated in the running community as a true-to-size baseline that delivers a comfortable and highly accommodating fit. When transitioning from the Ghost line to the Hoka Mach 6, runners can confidently maintain their standard size since both shoes align accurately on linear length expectations and target a well-proportioned daily training fit.

Nike Pegasus Series (Pegasus 41)

The Nike Pegasus series generally runs true to size, though certain iterations are noted for possessing a slightly narrow or streamlined midfoot and toe box footprint. To manage the width-versus-length compensation factor: if you have previously sized up a half-size in the Pegasus series solely to secure essential lateral relief for a wider foot profile, you may be able to return to your true length in the Mach 6, given that standard-width footprints correspond symmetrically across both models.

Brooks Adrenaline GTS

As a prominent stability trainer, the Brooks Adrenaline GTS provides a highly structured and firm underfoot sensation via its supportive guide rails, yet its overall physical length tracks true to standard sizing conventions. Runners transitioning to the neutral Hoka Mach 6 can expect a matching size profile in length, exchanging the rigid physical stability elements of Brooks for the lively and snappy compression attributes of Hoka's updated Performance Foam.
