Superior 6

Trail2023-06 · JP · Type unknownChecked 2026-10-16

Superior 6 is a low-stack trail model built around a 21 mm zero-drop platform for strong ground feel. Compared with the prior version, its upper adds ripstop and vamp mesh, while the MaxTrac outsole material and lug layout are revised for traction and durability. Compression-molded EVA, Standard FootShape, and the removal of the detachable StoneGuard keep the construction flexible for quicker trail runs and hiking.
