I tested my running economy in the Altra Vanish Carbon.
Testing Methods
I ran in each shoe as well as the Nike Alphafly and my typical control shoe (Asics Hyperspeed) for two reps each at 6:20/mile pace while measuring oxygen consumption and energy expenditure. Check out this link to see what running economy is, how it is measured, and how it impacts performance.
Results
When looking at the Altra Vanish Carbon from a performance perspective, I got about 2% benefit from the Altra compared to a 4% benefit from the Nike Alphafly.
Take Home Message
Very comfy shoe. Soft foam…reminds me more of the Puma Deviate Nitro Elite and New Balance RC Elite foam. I really like the wide toe box in the Altra, especially since I’m used to walking around in Xeros for my everyday casual shoes. Performance-wise, still not quite the pop, I get out of the Alphas though.
