Truth be told, the new Axiom 2 is a supportive yet lightweight trainer for slight to moderate overpronators. Its split medial Diagonal Rollbar (DRB®) provides just the right amount of pronation-correcting support while allowing torsional response, so it's not too stiff and allows natural movement. A cushioning combination of fluid-filled HydroFlow® units and a resilient Substance 257 midsole takes the pounding, so your feet don't have to.
