Saucony Endorphin Pro 4 - Blue - UK 13

The carbon fibre plate in the Endorphin Pro 4 provides exceptional stiffness and acts as a lever, working with the foam to create a highly propulsive feel. This enhances energy return and drives you forward, helping you maintain speed and efficiency during intense efforts and races.

While highly capable, the Endorphin Pro 4 is optimized for speed work, tempo runs, and racing. For everyday, easy training, you might find a more traditional daily trainer to offer better long-term comfort and durability. Using these exclusively for daily training may shorten their performance lifespan.

Speedroll Technology is Saucony's unique geometry that features an elevated cushioning and a stiff forefoot. This design creates a feeling of continuous momentum, propelling you forward and allowing for a faster, more efficient turnover with less effort.

Hand wash with mild soap and cold water. Use a soft brush to remove dirt. Avoid machine washing or using harsh chemicals. After washing, air dry them away from direct heat or sunlight, stuffing them with newspaper to help absorb moisture and maintain shape.

The lifespan of running shoes varies depending on mileage, running style, and surface. For high-performance shoes like the Endorphin Pro 4, a typical lifespan is around 300-500 miles. Beyond this, the cushioning and responsiveness, particularly of the foam and carbon plate, may diminish, affecting performance.

Yes, PWRRUN PB is a lighter, highly cushioned, and responsive foam used extensively in the midsole for comfort and bounce. PWRRUN HG is an even lighter, higher-rebound foam, often used in strategic areas or in conjunction with PB to maximize metabolic efficiency and provide an extra pop for ultimate speed.

Ensure your shoes are laced correctly and not too tight. Experiment with different lacing patterns. Make sure you are wearing appropriate running socks that wick moisture away. A break-in period might also be necessary.

Performance running shoes have a finite lifespan. If you've put significant mileage on them (typically 300-500 miles, but varies), the cushioning and carbon plate may have lost their effectiveness. Consider if it's time for a new pair. Also, ensure they are properly cleaned and dried after use.

Try using a 'runner's knot' or 'heel lock' lacing technique to better secure your heel. Ensure the shoe is the correct size; too large can cause slippage. The integrated tongue system and heel liner are designed for a secure fit, so re-evaluate your lacing.

While these shoes are cushioned, they are also designed for speed. Ensure your running form is efficient. If discomfort persists, consider if your feet are adapted to the aggressive geometry of a carbon-plated shoe. Gradually increase mileage in them.
