A middle child to Neutral and Support, the Ravenna 4 is leading
the charge for in-between feet. This season, this shoe is bringing a
whole lot of swagger with sleek design lines and fast colors. We’ve also
honed in on midfoot capture and engineered a saddle that envelopes the
foot with an adjustable band. Not too Neutral and not too Support, the
Ravenna 4 is juuust right.
Flextra-elements are strategically incorporated into the outsole in the forefoot area. These elements are designed depending on gender and weight to provide the necessary forefoot stability. Flextra is a system of individually configured flex grooves. It guarantees every runner ideal forefoot flexibility independent of weight and gender. Our product developers differentiate by using three different flex groove designs. The less outsole material is being utilized the more flexible the shoe becomes.
The new midsole material MoGo is an ingenious polymer structure that is more durable than EVA, offers a softer, more flexible running experience. Its properties are less temperature-related: Variations in rigidity are minimal at both high and low temperatures (+/- 0,15 Pa).
The new shock absorption technology benefits from optimal energy feedback. With conventional sole materials, the energy feedback peters out as the impact force rises. This is also the reason why some shoes feel kind of „flat“ after a certain period of time. Exactly the opposite applies with BROOKS. With BROOKS DNA™, higher impact forces also boost the energy feedback.
We constantly test how sustainable our materials are. This is why we added a green feature to the S-257 Cushsole.
Bio S-257 Cushsole is more sustainable than the conventional S-257 midsole material; just like our BioMoGo midsole, the Bio S-257 Cushsole decomposes a lot faster and is therefore considerably better for the environment. There's no difference in the materials’ performance though.
Great cushioning and excellent energy return guaranteed - while keeping tomorrow's runners in mind at the same time.
DRB™ counters the foot's tendency to pronate. It offers perfect control of the foot's transition from heel to toe.
