How to clean Saucony shoes: what you need to know about PWRRUN foam

The short answer: Hand wash with cold water and a soft brush. Never put Saucony shoes in a washing machine or dryer. Machine washing degrades PWRRUN foam by breaking down the foam cell structure, which permanently reduces cushioning performance.

The correct method

1. Remove the insole and laces — wash separately by hand.
2. Use a soft brush (an old toothbrush works) with cold water and mild soap.
3. Scrub the upper gently — mesh areas need light pressure only.
4. Wipe the midsole with a damp cloth — avoid soaking.
5. Clean the outsole rubber with the brush.
6. Air dry at room temperature, away from direct heat and sunlight.
7. Stuff with newspaper to hold shape while drying.

The insole

Remove the insole after every run if the shoe gets wet inside. Insoles left wet for extended periods develop odour and can degrade faster than the shoe itself.

Verdict
Hand wash only. Cold water. Air dry in shade. This single rule extends shoe lifespan significantly.
