Saucony Endorphin Pro 5 Trainers - White - Size UK 9.5

While excellent for race day and key long runs, they are primarily designed for speed. For the bulk of marathon training mileage, a more durable and cushioned daily trainer is often recommended to prevent excessive wear on the shoes and your legs.

PWRRUN PB is a very soft and lightweight foam. Super Critical PWRRUN HG is a firmer, more resilient foam. Combining them in the midsole creates a unique balance of soft cushioning with a firm, propulsive top layer.

The slotted design allows the plate to work more dynamically with the midsole and your foot's natural motion, enhancing the SpeedRoll technology for smoother, faster transitions and a more responsive feel.

The PWRTRAC rubber is engineered for a balance of grip and durability. While it offers reliable traction, its primary focus is performance, so it may wear faster than the outsole rubber found on more durable daily trainers, especially with frequent use on abrasive surfaces.

It is generally advised to reserve these shoes for their intended purpose: racing and speed workouts. Frequent use for everyday jogging can accelerate wear and may not provide the ideal cushioning or support for those types of runs compared to a dedicated daily trainer.

The product information lists this specific item as UK 9.5. It is recommended to consult Saucony's official sizing chart for precise measurements and fit guidance, as shoe sizing can vary between brands and models.

This is common with carbon-plated shoes. Wear them for a few shorter runs or workouts to allow the midsole and plate to break in and adapt to your stride.

The PWRTRAC outsole is designed for optimal grip on dry and typical race day conditions. Performance on extremely wet or slick surfaces may vary. Ensure shoes are clean of debris that could impede traction.

Ensure you are using a secure lacing technique, such as a double knot, especially if you have a tendency for laces to loosen. Consider replacing laces with a textured or lock-style alternative.

The shoe's design and plate may create a different feel. Try adjusting the lacing to relieve pressure points. If discomfort persists, these shoes may not be the best fit for your foot biomechanics.
