The little brother to the original 6mm Legacy; the exact same material used except in a typical insole thickness of 3mm. Has the same characeteristics as the 6mm including:
Dual-layer technology-Upper layer contours the foot which helps distribute weight over a greater area, leading to reduced pressure points and increased support and stability. Bottom layer reduces peak deceleration G-forces (which means greater shock reduction) and adds durability to the insole.
High performance moisture-wicking fabric on top pulls water away keeping your feet drier.
Material has high resistance to compression-set; it will not squish down over time like most memory-foam-type of insoles.
