When you're deep into a Sunday long run wearing the Adidas Solar Glide Boost Running Shoes, you'll swear those things are running on solar power. With ultra springy energy-returning Boost cushioning and lots of healthy support, these shoes will keep up their energy and comfort during your whole run. Key to the Solar Glides is the built in Solar Propulsion Rail, which helps to support and guide the foot as you stride. You've also got a specially molded heel that promotes a healthy and efficient motion of the Achilles, so achy ankles won't have you turning around early. A Stretchweb design in the outsole lets your foot flex naturally for better speed and efficiency, while durable Continental Rubber helps you grip wet and dry surfaces alike, so you won't be slipping around wet and cloudy weather rolls in.
