Don't be fooled by the adiStar's low weight and mesh upper. It's a solid motion-control shoe for heavier runners or severe overpronators looking to hammer out miles. Adidas recently streamlined its proprietary Ground Control System, resulting in a sleeker, lighter shoe with the same support benefits. It nips overpronation in the bud but without the boxy feel of many stability shoes. The ultralight mesh upper is reinforced, so you don't lose any support up top. 10.1 oz; www.adidas.comBonus: That mesh cools feet on the hottest days.Bummer: Some testers found the toe box too roomy, making it best for wider, higher-volume feet.
