The Rocket X 3 is a carbon-plated racer with a reputation for being more stable and less tippy than most super shoes, which makes it usable across a wider range of paces and distances than a typical race-day shoe.
It fits true to size with a dialled-in race fit. The single-layer engineered mesh upper, a more padded and structured heel counter and sawtooth laces combine for strong heel lockdown and midfoot hold. Reports on forefoot width conflict, with some finding it snug and others wide-foot friendly, so if you are between sizes or want extra room up front, half a size up is the common move.
Best for: Race day, half marathon through marathon
Sizing: True to size
Fit: Reports vary from snug to accommodating; standard width only
