Saucony - Endorphin Pro 5 Trainers - Orange - Size UK 5.5

The Endorphin Pro 5 is engineered for adult female runners focused on speed, particularly for race day or fast training sessions like tempo runs and intervals.

It features a dual-layer midsole: PWRRUN PB for a lightweight, bouncy base and Super Critical PWRRUN HG for a firmer, more propulsive top layer.

The slotted carbon fiber plate works with the SpeedRoll technology to enhance propulsion and create smoother, quicker transitions from heel-strike to toe-off.

While possible, the Pro 5 is optimized for speed. For daily easy or recovery runs, a shoe with softer cushioning might be more comfortable and suitable for preventing excessive fatigue.

SpeedRoll Technology is designed to reduce braking forces and create a forward-propelling sensation, making your stride feel more efficient and faster with less effort.

Clean with cool water and mild soap using a soft brush or cloth. Avoid machine washing and air dry away from direct heat.

The PWRTRAC rubber outsole is designed to provide reliable traction and durability on various road surfaces.

Ensure the shoes are properly laced and have been worn for a few runs to break them in. For some runners, the stiffness is a feature for propulsion; consider if this shoe type is the best fit for your running style and needs.

Check the PWRTRAC outsole for embedded debris. Clean the outsole. If wear is significant, the outsole may need replacement, or the shoe may be nearing the end of its lifespan.

Verify you have the correct size and width. Ensure socks are appropriate for running. If discomfort persists, the shoe's geometry or cushioning profile might not suit your biomechanics.
