For ambitious runners seeking a versatile shoe for both fast training and race days, the Saucony Endorphin Speed 5 delivers exceptional speed and responsiveness. Its lightweight design and advanced PWRRUN PB cushioning propel you forward, though its primary focus on asphalt and speed might mean it's not the softest option for every single casual run.

The Endorphin Speed 5 is best for speed training, tempo runs, interval workouts, and race days, from 5K to marathon distances. It truly shines when you're pushing the pace.
While it can handle moderate training, its design is optimized for speed and efficiency. For everyday slower runs or high-mileage base training, you might find a dedicated daily trainer offers more comfort and durability for those specific purposes.
The semi-rigid nylon plate in the Endorphin Speed 5 provides a propulsive feel and torsional rigidity, offering a more forgiving and slightly less aggressive ride than a full carbon fiber plate. This makes it a versatile option for both training and racing, often preferred for its blend of speed and comfort.
The Endorphin Speed 5 has an 8mm heel-to-toe drop, with a heel stack height of 36mm and a forefoot stack height of 28mm.
The PWRTRAC rubber outsole provides reliable grip on common running surfaces such as asphalt roads, track surfaces, and well-maintained park paths.
The men's version of the Endorphin Speed 5 weighs approximately 8.4oz (238g) for a US size 9.
Clean with a soft brush, mild soap, and cold water. Gently scrub away dirt and stains. Avoid machine washing or drying, as high heat can damage the materials. Always air dry your shoes away from direct sunlight or heat.
Ensure your laces are not overtightened. The mesh upper adapts, but if discomfort persists, consider trying a different lacing technique or verifying you have the correct size. Thinner socks can also help.
The SPEEDROLL Technology and nylon plate are most noticeable at higher paces. Try incorporating some faster segments or strides into your run to experience the full benefit. Ensure your running form is efficient, as these technologies complement good mechanics.
While the PWRTRAC rubber outsole provides reliable grip, no shoe is completely slip-proof on all wet or uneven surfaces. Reduce your pace and be cautious in slick conditions. Check the outsole for excessive wear, which can reduce grip.
