The Saucony Endorphin Speed 4 is highly regarded as an exceptional, versatile, and high-performance daily trainer. It improves upon its predecessor with a more accommodating fit, better stability, and improved traction, making it a great choice for runners seeking a responsive, snappy ride without the rigidity of carbon-plated super shoes. While it is slightly heavier and firmer than the v3, it remains a top-tier recommendation for speed work, tempo training, and long distance efforts.
