Saucony Omni 20 Women's Running Shoe Alloy, Jade S10681-20

An Extended Medial Post isn't subtle, and that's the point — the Omni 20 uses it to keep overpronators aligned mile after mile, backed by a TRI-FLEX outsole for a smoother ride and FORMFIT construction that hugs the foot in 3D. The outsole itself splits duty between iBR+ up front and XT-900 at the heel for durability where it matters most, all at 292g with an 8mm drop (34mm heel/26mm forefoot).

What does the Omni 20's medial post actually do? It's an extended, firmer piece of foam on the inner side of the midsole — the Saucony Omni 20 uses it to resist excess inward roll and keep your stride aligned.
