Air Cushion Midsole smoothes out footstrike and improves stride efficiency.

In the interest of durability and support with this Siren we stopped just short of nothing but net. But a breathable mesh upper and mesh lining go with the flow. Thin sculpted leather strapping provides lightweight but effective soft buttressing. Merrell's proprietary combination of women-specific Q-Form alignment in an Air Cushion Midsole smoothes out footstrike and improves stride efficiency.
