Salomon Index.01 Running Shoes Energetic and highly cushioned, the Salomon Index.01 Running Shoes are an ideal choice for any training session or race. These shoes are entirely realised from recycled materials, and their construction allows them to be quickly separated for easy recycling once they are worn out. A deep and plush Infiniride midsole is made from Dynamic TPU foam to be tremendously shock-absorbing and highly responsive. The lively stride pattern infused by this midsole is exaggerated by its R.Camber curved format that increases the efficiency and speed of heel-to-toe transitions. The grippy rubber of the outsole increases the runner's confidence by providing excellent traction across all road conditions. The breathable upper guarantees cooling ventilation in warm weather, and flat laces grant extra stability without causing pressure points across the top of the foot.
