Saucony Endorphin Pro 4 Trainers - White, Size 3.5

While highly responsive, the Endorphin Pro 4 are primarily designed for fast training, tempo runs, and race day due to their carbon plate and performance-oriented cushioning. For everyday easy runs, you might find a less aggressive trainer more suitable and comfortable, which also helps extend the life of your Pro 4s.

The integrated carbon fibre plate acts as a lever, working with the shoe's geometry to provide a propulsive feel. It helps maintain forward momentum, reduce energy loss, and can contribute to a faster, more efficient stride, especially at higher speeds.

The typical lifespan for high-performance running shoes like the Endorphin Pro 4 is generally between 300-500 miles. However, this can vary based on your running style, body weight, terrain, and how well you care for them. Pay attention to how the cushioning feels; if it loses its spring or you start experiencing new aches, it's likely time for a new pair.

It is generally not recommended to machine wash running shoes as it can damage the materials, adhesives, and cushioning. Instead, follow the care instructions: clean with a damp cloth and mild soap, and air dry naturally.

Saucony running shoes generally run true to size for most individuals. However, fit can be highly personal. We recommend trying them on with your usual running socks. If you're between sizes, consider opting for the larger size to ensure adequate toe room, especially for longer runs.

For optimal comfort and performance, we recommend wearing technical running socks made from moisture-wicking synthetic materials. These help prevent blisters and keep your feet dry, complementing the breathable upper of the Endorphin Pro 4.

High-performance shoes sometimes require a short break-in period. Start with shorter runs or walks to allow the shoe to adapt to your foot. Ensure you're wearing appropriate running socks and that the lacing isn't too tight or too loose. If discomfort persists, re-evaluate sizing.

The cushioning and carbon plate can naturally lose some responsiveness after extensive mileage. This is a normal sign of wear. Ensure proper care, including air drying and rotation if possible. If the shoes have accumulated significant mileage (typically 300-500 miles, depending on individual biomechanics and use), it might be time to consider a replacement.

Remove insoles after each run to allow them and the shoe interior to air dry thoroughly. You can sprinkle baking soda inside the shoes and insoles overnight to absorb odors. Wash insoles periodically with mild soap and water, ensuring they are completely dry before reinserting.
