What Our Gearhead® Experts Are Saying:"This shoe is built for fast training days. The FloatPro™ Supercritical Foam feels energetic underfoot, but what really impressed me is how stable and smooth the transitions are. It’s light, breathable, and has the grip to back up its pace."We lace up the Promorph Trail Running Shoe when we want to shave time, move light, and keep pushing personal records. With its engineered synthetic and mesh upper, this shoe keeps us cool and focused while maximizing breathability and comfort across long miles or high-speed workouts. Underfoot, the FloatPro™ Supercritical Foam midsole delivers ultra-responsive rebound with just enough cushion for endurance work, while FLEXconnect® grooves provide natural foot movement and connection with the road. Finished with a Vibram® XS Trek EVO outsole for adaptable grip on varying surfaces, the Promorph is everything we want in a high-mileage, performance-forward trainer.
