Designed for those who like the option of having a little extra protection. Take it out when you when want to feel the ground and put it in when you're pounding serious pavement. The Legacy has you covered with 6mm of protection.
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.
