Saucony Endorphin Pro 4 - White - 6.5 UK

The Endorphin Pro 4 is specifically designed for competition, race day, and high-intensity training sessions such as tempo runs, interval training, and speed work. It's built to help you achieve maximum speed and efficiency.

While capable, the Endorphin Pro 4 is highly specialized for speed and competition. For daily, easy-paced training runs, you might find a more cushioned, less aggressive shoe to be more suitable and durable for higher mileage.

This women's model weighs 212 grams (7.5 oz) and has an 8mm heel-to-toe drop, which contributes to its responsive and fast feel.

PWRRUN HG and PWRRUN PB are Saucony's advanced cushioning compounds. PWRRUN HG (High Grade) provides extreme energy return, while PWRRUN PB (Personal Best) offers lightweight, springy cushioning. Together, they create a dynamic and propulsive ride.

The full S-shaped carbon fiber plate acts as a stiffening element within the midsole. It works with Speedroll technology to create a lever effect, providing a powerful and continuous forward propulsion, making your stride more efficient and faster.

The Endorphin Pro 4 is optimized for running on asphalt and paved road surfaces, where its outsole material provides excellent traction and durability.

Yes, the Endorphin Pro 4 is highly capable for marathon distances. Its combination of high stack cushioning and propulsive carbon plate is designed to maintain efficiency and speed throughout long races, helping you push for personal bests.

The Endorphin Pro 4 features a carbon plate and high stack height designed for propulsion. If you're new to plated shoes, it may take a few runs to adjust. Start with shorter, faster sessions to get accustomed to the feel. Ensure your laces are not overtightened, which can exacerbate stiffness.

The shoes come with elastic laces. Experiment with different lacing techniques to find a secure fit. A double knot can prevent laces from coming undone during intense runs. If the elastic laces are too long, you might consider replacing them with standard running laces if preferred, though the elastic nature contributes to the adaptable fit.

The lightweight mesh upper is designed to be adaptable. Ensure you have the correct size. Adjust lacing tension across different parts of your foot. If the issue persists after several runs, it might indicate an incorrect fit, consider trying a different size or width if available.

Ensure you are using the shoes for their intended purpose: faster paces, tempo runs, or races. The energy return is most pronounced when running at higher speeds. Over time, cushioning can compress; however, for a new shoe, verify your running form is efficient, as Speedroll technology works best with a midfoot strike.
