Saucony Endorphin Pro 5 Trainers - Size UK 6.5

These shoes are primarily designed for speed and racing. While they can be used for some faster training sessions like tempo runs, they are generally too aggressive and specialized for everyday jogging or long, slow runs. A more cushioned, everyday trainer is recommended for those purposes.

The carbon plate works with the foam and rocker geometry (SpeedRoll) to create a stiff platform that enhances propulsion and promotes a faster transition through your stride. It helps to reduce energy loss and encourages a more efficient running form, particularly at higher speeds.

PWRRUN PB is a lightweight, high-rebound PEBA-based foam that provides excellent energy return. Super Critical PWRRUN HG is a denser, more supportive foam, often used in layers to provide structure and stability while maintaining responsiveness. The combination aims for a balance of cushioning, energy return, and propulsion.

You should have about a thumb's width of space between your longest toe and the end of the shoe when standing. The shoe should feel snug and secure around the midfoot and heel, with no excessive slipping or pinching. Try them on with the type of socks you typically run in.

The PWRTRAC rubber outsole offers decent grip, but extreme wet conditions can be challenging for any road shoe. They are suitable for running in light rain, but exceptionally slick surfaces may require caution. They are not designed for trail running.

For a performance racing shoe, the lifespan is typically measured in mileage rather than time. Expect to get anywhere from 200-400 miles (320-640 km) out of them, depending on your running style, weight, and the surfaces you run on. The midsole foam will eventually compress, and the outsole will wear down.

The Endorphin Pro 5 features a carbon plate designed for stiffness and propulsion. Ensure you are using them for their intended purpose (fast running, racing). Allow for a break-in period of a few runs to adapt to the shoe's ride. If still uncomfortable, they may not be the right fit for your biomechanics or preferred running style.

While the PWRTRAC outsole provides good grip, extremely wet conditions can challenge any rubber compound. Ensure the outsole is clean of debris. For significant wet weather running, consider shoes with more aggressive tread patterns if grip is a primary concern.

This could be due to improper sizing or the need for adjustment. Double-check that you have the correct UK size. Ensure laces are tied appropriately, not too tight or too loose. If the issue persists after a break-in period, the shoe's shape may not be compatible with your foot's anatomy.
