Like the original HFS, the HFS II is super lightweight (8.3 oz, M9) so you’ll feel like you’re flying down the road. And with a new tire tread-inspired outsole, you’ll feel secure even if you go off road.
HFS II is so comfy, you might forget to take them off at the end of your run – Xero Shoes even had people go to bed still wearing their shoes because they forgot they had them on!
