Brooks Trance 8 with the same top-of-the-line technologies that made its predecessor an award winner and make it more environmentally friendly. Women width B.

HydroFlow Dynamic viscous fluid units for heel and forefoot enhance midsole cushioning; attenuating shock with industry leading dampening and comfort.

BioMoGo Brooks has taken the long lasting cushioning of its MoGo midsole and made it environmentally friendly. By adding a non-toxic, natural additive to the MoGo compound that encourages anaerobic microbes to munch away once it hits the landfill.

e1 Midsole/outsole compound works in conjunction with HydroFlow and S-257 to progressively dampen the forces of energy that occur during the contact phase.

e2 Midsole/outsole compound is used to enhance resilience under the metatarsals, resulting in a more powerful propulsion.

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.

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 Cush sole Durable, energy-efficient midsole compound utilized as an insole board for even more cushioning and flexibility.

OUTSOLE HPR Plus; Engineered Stable Pod Configuration; Blown Rubber Forefoot

HPR PLUS A higher durability, abrasion-resistant rubber outsole compound that wears longer.
