The adidas Ultra Boost M ($175) is one of the best running shoes you can buy. They get their name from an incredible high rate of energy return provided by there Boost Technology foam midsole. The aforementioned midsole also gives you a grounded feel no matter the conditions. The shoe features a Primeknit upper with an external heel counter that flexes with every movement while locking you into the shoe for the snug sock-like feel. You also get a beautifully styled shoe that will go nicely with your favorite pair of joggers.
