Saucony Endorphin Pro 5 Trainers - White - Red - Size UK 13

These shoes are designed for serious runners, particularly adult males, who are looking to maximize their performance on race day and achieve personal bests. They are best suited for distances from 5K to marathons.

The Pro 5 features a slotted carbon fiber plate and advanced foam technologies (PWRRUN PB and Super Critical PWRRUN HG) integrated with SpeedRoll technology, all designed to provide maximum propulsion and efficiency, which is not typically found in standard daily trainers.

The shoe should feel snug but not tight, with about a thumb's width of space between your longest toe and the end of the shoe. Ensure your heel is secure and there's no excessive slipping.

While you can use them for some faster training runs (like tempo or interval sessions), they are primarily optimized for race day. For very high mileage daily training, a shoe with more emphasis on long-term durability and comfort might be more appropriate.

The carbon plate is engineered for the lifespan of the shoe under typical racing conditions. It is not expected to degrade or lose its effectiveness with normal use during races and faster training runs.

Regular cleaning involves brushing off dirt and air drying. Avoid machine washing or using harsh chemicals. Proper care ensures the longevity of the shoe's performance features.

The PWRTRAC outsole provides good traction. However, extreme wet conditions may reduce grip. Use caution on slippery surfaces and be mindful of the conditions during your run.

This can be common with carbon-plated shoes. Ensure you have the correct size and allow for a break-in period of a few runs to adapt to the SpeedRoll technology and plate.

While the PWRTRAC outsole offers good grip, extremely wet or slick conditions may still pose a challenge. Use caution and reduce speed if necessary.

Sometimes pebbles can get lodged in the outsole grooves. Check the outsole for debris and clean if necessary. If the noise persists, it may be an internal construction issue.

The combination of foams and the carbon plate provides responsive firmness. If it feels too firm, ensure you are running at a faster pace where the shoe's technology is most effective. For slower runs, consider a different shoe type.
