Saucony Endorphin Pro 4 - Blue - UK 9

The Endorphin Pro 4 is designed for dedicated athletes and competitive runners with a neutral pronation who are looking for maximum speed, efficiency, and energy return for race days and high-performance training sessions.

These shoes are specifically optimized for asphalt and road surfaces, providing optimal grip and performance on paved roads during races and fast training runs.

The dual-cushioning system combines PWRRUN PB and PWRRUN HG foams, offering a unique blend of softness, responsiveness, and exceptional energy return. This combination creates a more dynamic and propulsive ride, enhancing speed and efficiency.

SPEEDROLL Technology is Saucony's 'always-on' geometry with an elevated cushioning and a stiff forefoot. It creates a smooth, propulsive ride that feels effortless, encouraging faster transitions and forward momentum.

While capable, the Endorphin Pro 4 is optimized for competition and high-performance training. Its specialized design and materials are geared towards speed and efficiency, making it less ideal for high-mileage daily training runs where durability and different cushioning properties might be preferred.

The Saucony Endorphin Pro 4 has a stack height of 39.5mm in the heel and 31.5mm in the forefoot, resulting in an 8mm offset (heel-to-toe drop).

Yes, the Saucony Endorphin Pro 4 is made with vegan materials and incorporates recycled components, demonstrating an commitment to more sustainable practices.

The Endorphin Pro 4 features a high stack height (39.5mm/31.5mm) and a carbon plate, which can feel different. Allow a few runs to adapt to the shoe's unique geometry and propulsive feel. Ensure proper lacing for a secure midfoot lockdown.

High-performance foams and carbon plates have a lifespan. Reduced responsiveness can indicate the shoes are nearing the end of their optimal performance life, typically around 250-400 miles for race-day shoes. Also, ensure they are stored properly and not subjected to extreme heat.

While designed for comfort, individual foot shapes vary. Double-check lacing to ensure it's secure without being too tight. Experiment with different running socks, ensuring they are moisture-wicking and have adequate cushioning to prevent friction. If discomfort persists, check for any debris inside the shoe.
