The Saucony Endorphin Speed 4 is a versatile running shoe designed to optimize your performance across various types of runs. Its core strength lies in combining PWRRUN+ foam for resilient cushioning with SPEEDROLL technology for a propulsive, efficient stride. This makes it particularly effective for: - Tempo Runs: The shoe's snappy feel and forward-rolling sensation help maintain higher paces comfortably. - Speed Work/Intervals: The lightweight and responsive nature makes it easy to pick up the pace and sustain efforts during track sessions or fartleks. - Longer Training Runs: While built for speed, the generous PWRRUN+ cushioning provides enough comfort and protection for sustained efforts over moderate to long distances. - Race Day: Many runners find the Endorphin Speed 4 a capable race shoe, offering a balance of cushioning for endurance and propulsion for speed, making it a strong alternative to carbon-plated super shoes for some.When running, the SPEEDROLL technology works by creating a rigid forefoot with an elevated toe spring, encouraging your foot to roll forward quickly through your stride. This works in harmony with the PWRRUN+ foam which provides a springy, comfortable platform underfoot without feeling overly soft. The textured grip tread on the durable rubber outsole ensures reliable traction, allowing you to focus on your pace without worrying about stability on typical road surfaces.

Setup, Compatibility & Care### Setup1. Lacing: Unbox your Endorphin Speed 4 shoes. Loosen the laces completely. 2. Insertion: Slide your foot into the shoe, ensuring your heel is comfortably seated in the heel cup. 3. Adjustment: Begin tightening the laces from the bottom (closest to your toes) upwards, ensuring a snug but not overly tight fit. Pay attention to the padded tongue and cuff to ensure they lie flat. 4. Knot: Tie your preferred running knot, ensuring it's secure but allows for natural foot movement without restriction.### Compatibility- User: Designed for adult female runners. - Fit: The UK size 5 is a standard fit for this specific variant. Ensure you confirm your shoe size, as running shoe sizes can sometimes vary slightly between brands. - Running Surface: Primarily designed for road running and track surfaces. While the textured grip offers good traction, it's not intended for technical trail running.### Care- Cleaning: To maintain the integrity and appearance of your shoes, clean them regularly. Remove loose dirt with a soft brush (like an old toothbrush). Mix a small amount of mild soap with cool water. Dampen a cloth or sponge and gently scrub the upper and outsole. - Drying: Air dry your shoes completely at room temperature. Do NOT use direct heat sources like radiators, dryers, or direct sunlight, as this can damage the materials and adhesives. You can stuff them with newspaper to absorb moisture and help maintain their shape. - Storage: Store your shoes in a cool, dry place away from direct sunlight when not in use. Avoid storing them in extreme temperatures. - Maintenance: Check laces periodically for wear and replace if necessary. Avoid machine washing or drying, as this can degrade the materials and construction.
