The Right Shoes for Your Run
Whether you’re training for a marathon or just adding running to your regular fitness routine, shoes are the most important piece of equipment for both the casual and competitive runner. The right shoes can help cushion and support your feet — and even maximize the energy returned to you with every step — while the wrong shoes can lead to blisters, foot pain and worse.
Polyurethane is used throughout running shoes in a variety of ways to improve their durability and performance: Polyurethane adhesives are used to attach the sole to the shoe. They may be molded to the outer sole or added to the midsole layer to provide shock absorption. And polyurethane foam inserts and gels provide comfort and support.
Unlike other materials that are used for cushioning in running shoes, polyurethane foam does not break down as quickly. Thermoplastic polyurethane (TPU) is also durable and can provide temperature resistance and enhanced energy return.
