The Adidas Hagio is a racing flat that doesn’t mess around - it just delivers wins with its featherweight, flexible ride.
Though the Hagio is considered a replacement for the much-loved adizero Rocket, it's really the adizero Pro reborn. It's nearly an ounce lighter than the Rocket and feels much more stripped-down than that shoe. But don’t worry, the responsive ride that gave the Rocket such a fast feel is alive and well in the Hagio. “Like butta” is the best way to describe the shoe’s smooth transition.
The Hagio is a case in point for anyone claiming that you can run fast and remain comfortable. Elite runners will cover the marathon in this shoe, but for most runners this is an ideal shoe for 3K to half marathon distances.
One surprising feature of the Hagio is how grippy its outsole is, particularly in the forefoot. This is a big help at speed, giving you confident traction at toe-off. It’s also a nice feature to help you feel reassured if race day conditions are on the rainy side. We like the highly breathable mesh on the upper, and the fact that you can easily wear this shoe sockless without getting blisters all over the place.
So is this the perfect racing flat? Well, not quite. Out of the box, the laces are laced "backwards," making them difficult to tighten easily. It's easy to fix this problem - just undo the laces and string 'em up correctly. Some testers found the Sprint Web overlays in the midfoot to be too constricting, and others thought the forefoot was a bit too generous.
All told, the Hagio deserves the huge heap of praise it has received since its January 2012 launch and is a big win for Adidas in the lightweight racing flat category.
No doubt the Hagio feels light, but it didn’t feel quite as fast as I was expecting.
I can see why so many customers rely on the Hagio come race day. This shoe fits the niche of a lightweight racer to a T.
One of the best transitions of any running shoe I’ve tried out.
