    I'm not sure whether this is a lacing issue (although I lace them fairly tightly), whether they are actually a little too big, or whether I'm just still not used to the more minimal level of cushioning that these shoes have.

FTHR Radiate size and fit

The Under Armour FTHR Radiate is true to its size. It provides a snug fit, making sure that it will just fit right for the entirety of your run. Because of the Molded MPZ heel panel, it actually offers a lockdown fit, as well as support and protection. This shoe is available in standard running shoe width.


The FTHR Radiate features the solid rubber traction compound. Slipping off the ground is less likely to happen because of the great traction that this shoe offers. This rubber compound is also durable, giving endurance to high wear areas.


The Under Amour FTHR Radiate consists of the Micro G midsole both in the heel and forefoot. These protective contact pads are strategically positioned to help absorb impact while providing compression support. With its presence, you will be able to feel the road while running and at the same time, it still provides speed, grip and cushion.

In addition, the low heel and forefoot midsole also allows the foot to strike on forefoot or mid-foot. Running will be much better and smoother because of the improved midsole.


For the upper portion of this shoe, it features the molded Neoprene upper that is light and tough, which allows the foot to move naturally on the road. Because of the features included in the upper, the shoe makes you comfortable and well-cushioned all throughout your run.
