Saucony - Endorphin Pro 5 - Black - Trainers - Size UK 13

The Endorphin Pro 5 is primarily designed for fast running and race days due to its aggressive geometry and responsive cushioning. While it can be used for some faster training runs, it may not offer the same level of comfort or durability for daily mileage as a dedicated trainer. It's recommended to rotate it with a more cushioned or versatile shoe for everyday runs.

The Endorphin Pro 5 features a combination of advanced midsole foams (PWRRUN PB and Super Critical PWRRUN HG), a slotted carbon fiber plate, and the SpeedRoll technology. This setup is optimized for maximum energy return, propulsive feel, and efficient transitions, making it ideal for speed and racing, unlike many standard trainers focused more on general comfort and durability.

The Endorphin Pro 5 generally requires minimal break-in time due to its performance-oriented design. It's recommended to wear them for a few shorter runs to get accustomed to the feel of the carbon plate and SpeedRoll technology before committing to a long run or race.

The Endorphin Pro 5 has a standard width fit. While the engineered mesh upper offers some flexibility, runners with significantly wide feet might find them snug. It's advisable to try them on if possible or check reviews for specific feedback on width.

The carbon plate adds stiffness and responsiveness to the shoe. In the Endorphin Pro 5, it works with the SpeedRoll technology to create a propulsive sensation, helping to roll you forward and reduce the effort needed for toe-off, promoting a faster and more efficient stride.

For optimal performance, most runners find that shoes with advanced foams and plates like the Endorphin Pro 5 perform best within the 100-300 mile range. However, the exact lifespan can vary based on running surface, individual biomechanics, gait, and how the shoes are cared for. They are best reserved for key workouts and races to maximize their performance life.

Ensure the laces are not over-tightened. Try different lacing techniques to relieve pressure points. If the issue persists and it's not a sizing problem, consider if the shoe's aggressive geometry is suitable for your foot type or running style.

Advanced foams can degrade with extensive use. Ensure you are not using the shoes for excessive everyday training and are following care instructions. Mileage and impact will naturally affect foam performance.

While the PWRTRAC outsole offers good grip, extreme wet conditions can challenge any outsole. Ensure your stride is controlled and be cautious on wet painted lines or manhole covers. Regular cleaning of the outsole can help maintain optimal traction.

This can sometimes occur with new shoes due to air trapped between layers. Try flexing the shoe gently. If the noise persists and is distracting, ensure no debris is caught in the outsole tread.
