Brooks Men's Ravenna Running Shoes

Features:
HydroFlow® Dynamic viscous fluid units for heel and forefoot enhance midsole cushioning—attenuating shock with industry-lead¬ing dampening and comfort.
BioMoGo Our new midsole compound provides a soft cushy first feel that lasts—without sacrificing stability. In-house and accredited third-party testing showed that in comparison with Substance 257, MoGo offers a 40% increase in cushioning, 22% more energy return, and 33% less fatigue and will breakdown faster in a landfill when you’re done with them for good.
Diagonal Rollbar (DRB®) A high-density post at the medial arch is engineered for pronation control and creates a smoother transition from the midstance phase into the propulsion phase.
DRB® Accel Enhances tunable torsion of the midfoot. Shanklike thermoplastic devices vary from single units of a set modulus, to dual unit versions of varied modulus (one tuned with higher stiffness for medial support, the lateral side less stiff to smooth the ride).
S-257 Cushsole Durable, energy-efficient midsole compound uti¬lized as an insole board for even more cushioning and flexibility
HPR This durable rubber outsole compound offers higher perfor¬mance than standard carbon black compounds.
Engineered Stable Pod Configuration Midsole and outsole com¬ponents are engineered to set the foot up in an efficient, balanced position from heel strike to toe-off, offering maximum stabilityand responsiveness.
