R.A.D
Mallow
A high-stack cushioned daily trainer with a 42 mm stack of SwellFoam, a bio-based EVA and OBC blend, on a broad platform with a toe rocker and full rubber outsole. Testers found it soft, smooth and very stable at easy paces and good value, but heavy for its class.
About the Mallow
Third in R.A.D's running line, after the UFO and Synth, the Mallow arrived in May 2026 as the brand's high-stack cushioned trainer. R.A.D presents it as a supportive daily trainer for everyday miles, faster sessions and longer efforts. It shares the 42 mm heel stack and 8 mm drop of the PEBA-based UFO, but uses a different foam and is the heaviest of the three.
That foam is a version of SwellFoam made from 40% bio-based EVA and olefin block copolymers (OBC), which R.A.D says gives a cushioned ride on a stable platform. A dynamic toe rocker works with the heel stack, according to the brand, to help carry the runner forward, and a full rubber outsole covers the base. The engineered-mesh upper adds a heel clip for stability and plush collar and tongue materials. It comes in a single standard width.

Believe in the Run's Karl Fernandez and Meaghan Murray liked its soft cushioning and lockdown, but both felt its weight and Meaghan's toes sat at the very end.

What it feels like
Fit
True to size
Testers found it true to size for narrow to medium feet, but the toe box is pointed and one tester's toes sat at the end, so R.A.D's half-size-up advice makes sense for wide feet or long runs.
