What Our Gearhead(R) Experts Are Saying:"This shoe is built for fast training days. The FloatPro(TM) 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.
