The Brooks Defyance 4 running shoes are a neutral shoe delivering exceptional amounts of technology and sleek styling. Similar to the Adrenaline GTS in terms of fit, feel and balance it is given a further lift with medial DRB Accel for a smooth ride with a touch of support. The Defyance shoe has been developed further and now features a caterpillar crash pad that creates a smooth, adaptable transition from heel to toe while an asymmetrical arch saddle makes for a secure fitted mid-foot wrap. For superb cushioning and a purposeful ride its midsole construction features rearfoot HydroFlow ST, forefoot HydroFlow, full-length Bio MoGo, dual-density DRB Accel, and S-257 Cushsole. The combination of an HPR Plus, forefoot stable pod construction and blown rubber forefoot outsole with moisture management element mesh/linings, ortholite sockliner, internal support saddle and synthetic overlay materials in the upper provides excellent feel, traction and durability.
