Fit
The heel cup and ankle collar fit the heel securely and comfortably. There is very little widening toward the front of the Hyperion, although the one-piece upper is made of perforated stretch woven fabric that expands slightly to accommodate wider feet. The result is an upper that wraps your foot like a sock while running, and a traditional lace system secures the entire foot well. Length is true to size. 

Comfort
A very thin tongue shaves weight without sacrificing comfort when tied down tightly by the laces. The seamless upper of the Hyperion is highly flexible to move naturally with your foot, and has extensive perforations in the toe box and medial midfoot to facilitate air movement and cooling. Our testers were impressed by how effectively impact forces are absorbed on such a low platform. 

Responsiveness
Brooks sticks with its tried and true BioMoGo DNA midsole material that dynamically adapts to impact to provide the ideal amount of cushioning: softer when you’re running easy, firmer when you’re hammering. Our testers reported an ideal combination of quick energy return from the Hyperion without being bouncy. The BioMoGo material is shaped into propulsion pods in the forefoot that can flex and absorb impact independently for more efficient energy transfer.

Ride Quality
In addition to the propulsion pods, a firm midfoot transition zone provides smooth transfer of energy from rearfoot to forefoot. The 10mm drop helps generate forward momentum, and the flex grooves in the forefoot help the Hyperion continue a smooth transition before a final spring at toe-off. 

Speed
Speed is the name of the game with the Hyperion. Combine the super light weight, outstanding energy return, smooth ride, and 10mm drop, and you’ve got all the structural elements to bust a PR. The only minor drawback is that sparse outsole rubber on the bottom surface results in unsteady grip in wet or loose gravel conditions.
