Saucony Endorphin Pro 5 - Black - Size UK 10.5

The primary benefit is its ability to enhance speed and efficiency through a combination of lightweight, responsive cushioning, a propulsive carbon plate, and SpeedRoll technology, designed to help runners achieve their personal bests.

While durable, the Endorphin Pro 5 is optimized for speed and racing. For daily training focused on building mileage or recovery, a shoe with more cushioning and a less aggressive design may be more suitable to prevent excessive fatigue.

Clean them with a soft brush to remove loose dirt. For tougher grime, use a damp cloth with mild soap and water. Avoid machine washing and harsh detergents, and always air dry away from direct heat.

The slotted carbon fiber plate works with the SpeedRoll technology to create a natural forward-rolling sensation, promoting smoother, quicker transitions and improving running economy for faster paces.

The PWRRUN HG is a supercritical foam designed for responsiveness and energy return, contributing to a firm yet propulsive feel that aids in explosive takeoffs.

The PWRTRAC rubber outsole is designed for optimal grip and durability on road surfaces. It performs well in both dry and slightly wet conditions.

The Endorphin Pro 5 generally offers a snug, performance-oriented fit to keep the foot secure at high speeds. It is recommended to try them on or consult sizing charts for the best fit.

Ensure you have laced the shoes properly, not too tight or too loose. Try a short run to allow the shoe's foam and plate to adapt to your foot and gait. Consider if the shoe's aggressive geometry is suitable for your typical running style.

The PWRTRAC outsole offers good grip, but like all performance outsoles, caution is advised on very wet or slippery surfaces. Ensure the outsole is free from debris that could compromise traction.

Sometimes new shoes can have a brief squeaking period. This may resolve with use. If persistent, check for any small stones or debris lodged in the outsole or between the midsole layers. Ensure no parts of the shoe are rubbing abnormally against each other.

This could indicate the shoe's aggressive nature requires a gradual adaptation period. Try wearing them for shorter distances initially and gradually increase mileage. Ensure the fit is correct; a shoe that is too tight or too loose can cause fatigue.
