Saucony Endorphin Pro 4 - UK 7.5

The Endorphin Pro 4 is designed as a dedicated racing shoe, ideal for tempo runs, interval training, and competitions ranging from 5K to marathons on roads and tracks.

While it can be used for some faster training sessions, it is primarily a race-day shoe. Its aggressive design and specialized cushioning are best reserved for performance-focused efforts to maximize its lifespan and benefits.

PWRRUN PB is Saucony's premium cushioning foam, known for its high energy return and lightweight properties. SPEEDROLL Technology is an elevated cushioning and a stiff forefoot that propels you forward, creating a feeling of continuous momentum.

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

Gently hand wash with mild soap and water, using a damp cloth to wipe down the upper and outsole. Do not machine wash or tumble dry, and allow them to air dry away from direct heat.

The lifespan of running shoes varies by individual use, running style, and weight. As a specialized racing shoe, its durability for very high mileage might be less than a daily trainer. Using it primarily for races and speedwork will help extend its life. Info needed: [Saucony's recommended mileage for racing shoes]

Saucony generally designs its shoes to be true to size. However, fit can be subjective. We recommend trying them on to ensure a comfortable and secure fit, especially with performance shoes. This specific model is a UK 7.5 (Female).

The high stack and carbon plate can feel different. Allow for an adjustment period. Ensure laces are securely tied for optimal lockdown. If persistent, check your running form or consider if this specialized shoe suits your biomechanics.

The elastic laces are designed for comfort but can loosen. Try double knotting them for extra security before your run.

Ensure you are engaging the SPEEDROLL technology by maintaining a forward-leaning posture and quick turnover. The shoe works best with an efficient running form. Also, ensure the shoe is properly broken in with a few faster efforts.

Re-evaluate your lacing technique to ensure a secure midfoot lockdown. If the issue persists, you might need to adjust your sock choice or consider a different size.

Check your lacing for any overly tight spots. Ensure your socks are seamless and well-fitting. Break-in the shoes gradually. If discomfort persists, consult a running specialist for a fit assessment.
