You might be surprised to find that footwear named after a supernova can actually keep you feeling pretty cool. This shoe's mesh upper allows for great air circulation. And while that's a nice feature, the real star of the show here just might be the Supernova's thermoplastic polyurethane cushioning foam. These cheap, comfortable Adidas shoes are a wise choice for neutral runners who want a roomy toe box. The Supernova is related to the Addias' Glide line, so if you appreciated those previous models, you'll likely come to enjoy this one as well.
