Water resistant material with a hydrophobic foam interior to draw moisture away from the foot. An internal support saddle aids stability on uneven terrain. 360 Degrees of 3M™ Scotchlite™ Reflectivity.
Sole
Forefoot HydroFlow and Heel HydroFlow ST, Brooks' dynamic viscous fluid units for heel and forefoot enhance midsole cushioning-attenuating shock with industry-leading dampening and comfort. Full Length MoGo, Brooks' 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. Progressive Diagonal Rollbar-(PDRB™), Brooks' dual density post is biomechanically engineered to allow for progressive pronation control and creates a smoother transition from the midstance phase into the propulsion phase. Dual Density DRB Accel Enhances tunable torsion of the midfoot. Shank-like 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 is durable, energy-efficient midsole compound utilized as an insole board for even more cushioning and flexibility. Engineered Stable Pod Construction; Midsole and outsole components are engineered to set the foot up in an efficient, balanced position from heel strike to toe-off, offering maximum stability and responsiveness. HPR PLUS™ is a higher durability, abrasion-resistant rubber outsole compound that wears longer. HPR Gren™ is a durable and long-wearing outsole compound is made with dispersed silica, resulting in premium wet-dry traction for excellent skid-resistance and a more environmentally friendly composition.
