The PUMA Deviate Nitro Elite 4 is a top-tier racing shoe designed for marathoners seeking a blend of speed, comfort, and performance. It boasts a lightweight yet responsive ride, thanks to its innovative use of NITRO ELITE foam and a carbon-based PWRPLATE. The shoe's midsole delivers a balanced feel with a measured softness of 37.0 AC, providing a quick and immediate response underfoot. The high stiffness created by the PWRPLATE enables a pronounced rocker, ensuring smooth transitions and a controlled ride. The Deviate Nitro Elite 4 features a neutral racing design, with a forefoot that feels the most stable and a narrow midfoot and heel that require a polished running technique. The shoe's traction is dependable, thanks to the PUMAGRIP compound, which offers excellent grip on wet asphalt. The outsole, with minimal rubber coverage, prioritizes performance and provides confident toe-offs and sharp cornering at high speeds. The upper, made from ULTRAWEAVE, is highly breathable and lightweight, with oversized ventilation holes that enhance airflow. The tongue is surprisingly plush, offering an unusually padded feel for a super shoe. The Deviate Nitro Elite 4 is priced at $250, making it a reasonable option compared to models like the Vaporfly and Adios Pro, while still sitting one tier below the ultra-premium Fast-R series. Overall, it's a solid choice for runners seeking a fast and bouncy ride, but it may not be the best fit for heel strikers due to the narrow heel and limited stability in the rear.
