Traditional rubber outsoles are durable, but they're heavy. And for too long, that trade-off has just been accepted as the cost of grip. We don't accept it.
Our CPU outsole blends PU polymer with synthetic rubber to give you something better than either material alone: traction that doesn't quit, abrasion resistance built for serious mileage, and 10 fewer grams than our standard rubber sole. That last part matters more than it sounds.
Ten grams compounds. Lighter means less fatigue, eaiser form, and more left in the tank when it counts.
New on the Alma Cruise
Now it's standard across the entire Spring 2026 Alma collection.
The Tempo and Speed have always run on it. The Cruise just got the upgrade — without giving up a single thing that makes it worth lacing up in the first place.
The Alma Cruise was already built for distance. Now it carries less weight doing it.
