Pro-Specs launches Infinite Rush Rev. carbon racing shoe with enhanced rebound and propulsion

South Korean sports brand Pro-Specs has launched the Infinite Rush Rev., a carbon racing shoe featuring a higher-PEBAX midsole and a wide carbon plate.

The shoe follows the original Infinite Rush and targets runners looking to set personal bests.

The most significant change is the midsole material. Pro-Specs raised the PEBAX content in its SuperFoam+ compound from 40 percent to 100 percent. PEBAX is a high-performance material known for its light weight and exceptional elasticity. The company said the update delivers stronger energy return and rebound.

A wide carbon plate is also integrated into the sole to convert energy generated at landing into propulsion for the next stride. The shoe weighs 225 grams in a size 270mm.

Pro-Specs also improved fit and running stability. The last — the form that determines the shape of the shoe — was redesigned, and the forefoot and midfoot outsole were widened to reduce lateral movement at landing. The shoe incorporates a toe-spring geometry tuned to the running motion, a SuperFoam insole, and laces engineered to stay tied during a run. It comes in two colors: blue and yellow.

"The Infinite Rush Rev. strengthens rebound and propulsion for runners chasing new records, while also carefully improving fit and stability," a Pro-Specs official said.
