The new Altra Paradigm 4.5 continues to provide max cushioning from the Altra EGO™ midsole and a modern fit from a knit upper construction. Taking a unique stance on guidance, the Paradigm uses integrated StabiliPods™ for a stable platform and uses a GuideRail™ system to provide support when you need it, but not when you dont. An asymmetrical design with a medial flaring helps enhance lateral support for neutral and non-neutral runners alike.

Upper: Updated knit upper for ultimate, breathable flexibility. Padded heel collar enhances comfort. Flat laces reduce irritation.

Midsole: AltraEGO™ midsole for stable cushioning. Zero Drop™ places the heel and forefoot the same distance from the ground to encourage natural, low-impact running form. Features a GuideRail™ for further stability.

Outsole: Integrated StabiliPods™ provide further support.
