“HFS” may be short for “Happy Feet Shoes,” “Hyper Flexible Soles,” or, more likely, what you’ll exclaim when you try this 7.0 ounce (M9) true road runner, “Holy ___ ___!” Your feet will love the natural comfort of the wide toe box and zero-drop design. The tire-inspired tread keeps you sure-footed. The 37.5® sockliner and breathable engineered mesh keep you cool. Hidden instep and mid-foot tensioners give you the security you need to go for that new personal best.

Cute and comfy
I bought the grey style and liked them even better in person. I've had a few complements too. But, that nothing compared to how comfortable they are right from the first time I wore them. They are now my second favorite shoes - a close second behind my Genesis sandals.
