Introducing the NFS (Natural Foot Shape) Insole.
Designed around the natural foot shape popularized by Altra and engineered specifically for wide toe box footwear, the NFS gives your feet the room they were meant to have without sacrificing comfort or support.
Built on a zero-drop platform, the NFS helps keep your foot in its most biomechanically neutral position, stride after stride. A responsive PU foam top layer delivers energy return without feeling mushy or bottoming out, while a textured non-slip EVA base keeps the insole securely in place through long runs, hikes, and everyday wear.
At 5.5mm thick, the NFS adds protection and rebound without changing the fit your shoe was designed for.
Coming Late Summer 2026.
