Saucony Endorphin Pro 4 - Blue - UK 9.5

The Endorphin Pro 4 is optimized for race days and high-performance training sessions such as tempo runs, interval training, and long runs where speed and efficiency are the primary goals.

While capable of handling some faster daily training, its specialized design for speed and energy return makes it less ideal for everyday, easy-paced training or recovery runs where maximum cushioning for comfort is often preferred.

The dual-cushioning system combines PWRRUN PB and PWRRUN HG foams. This blend provides a soft landing with exceptional responsiveness and energy return, working with the carbon plate to propel you forward efficiently.

Speedroll Technology is an always-forward geometry that gives you a lively, rolling sensation underfoot. It promotes effortless speed and a propulsive forward motion, helping you maintain momentum and reduce fatigue at faster paces.

The Saucony Endorphin Pro 4 features a 39.5mm stack height and an 8mm offset (heel-to-toe drop).

Gently brush off loose dirt. For deeper cleaning, use a mild soap and cold water with a soft brush or cloth. Avoid machine washing or drying, as this can damage the materials and construction. Always air dry completely.

Yes, this style is vegan and contains recycled materials as part of Saucony's commitment to sustainability.

The Saucony Endorphin Pro 4 weighs 212g, making it a lightweight option for performance running.

Ensure you've completed a few runs to break in the shoe. The carbon plate and foams require a short adaptation period. Also, verify your lacing isn't too loose, which can prevent your foot from fully integrating with the shoe's dynamics.

Re-evaluate your lacing. Try a 'heel lock' lacing technique to secure the ankle and prevent heel slip. Also, ensure you are wearing appropriate running socks that prevent friction and add minimal bulk.

This could be due to ill-fitting socks, excessive moisture, or slight size mismatch. Ensure your socks are moisture-wicking. Check if any particular seams in the shoe are rubbing; adjusting lacing can sometimes alleviate this. If discomfort persists, verify your shoe size, as running shoes often require a half-size up from casual shoes.

This is often caused by friction, typically between the insole and the shoe's lasting board, especially if moisture is present. Remove the insoles and air them out. You can also try sprinkling a small amount of baby powder or talcum powder under the insoles to reduce friction.
