Running Shoes
Athletic footwear designed for running and jogging, featuring cushioned soles, synthetic uppers, and often waterproof or water-resistant treatments.
Why It Matters
Feet sweat heavily during exercise, increasing chemical absorption. Rubber soles may contain PAHs (carcinogenic compounds in rubber). Synthetic materials and waterproof treatments often contain PFAS. Foam cushioning may contain plasticizers.
