Under Armour has made an analogy that I have never heard before: A shoe that acts as a bra for your feet. The senior creative director of footwear says that the company is “changing the way footwear is made”. The Speedform is not made in a footwear factory. These seamless shoes that are said to be made to the anatomy of the foot are manufactured in a bra factory in China.
This is possibly the start of a new feel and fit for running shoes. The current models are for racing, but more cushioned versions and planned for the future.
I have no opinion on these shoe at this time and as always I advise caution. The current model is akin to a minimalist shoe so if you have an unstable foot these are not for you.
