Update (November 2024): The Blue Aster colourway is no longer available and Asphalt Alloy is low in stock at Xero so sizes will be limited for restocking.

Xero Shoes has taken their best-selling roadrunner and updated it, resulting in their Fall/Winter 23 release: the HFS II. 

Note: the sizing has been updated from the original to be closer to true-to-size. Scroll to sizing for details.
