If you've taken a running hiatus recently, trading outdoor miles for studio classes and more nights out with your friends, relax. Everyone's done it at some point. But if spring and summer goal races have started sneaking their way into your thoughts, slip on the Adidas Women's Ultraboost Running Shoes to get yourself back into the sport you love. Adidas' proprietary Boost cushioning is the star of the show here, lending the Ultra Boost a springy, energetic pop and nimble feel. Slipping on your shoes and warming up is always the toughest part of returning to running. Fortunately, when you slip on the Ultra Boost, the stretchy Primeknit uppers conform to the lumps and bumps of your feet, while Adidas' Torsion system locks in a secure fit along your instep and provides stability through the middle of the shoe. Along your heel, FitCounter wraps around your Achilles tendon, allowing it to flex and extend naturally throughout the course of your run. While Boost cushioning creates a soft, but responsive ride, Continental and StretchWeb rubber along the outsole add grip and durability as you gradually build up your miles.
