Review: Under Armour Slingflex

Clap. Clap. Clap. Kudos, Under Armour, for making a damn fine runner. I’m actually embarrassed how much I liked this shoe. It’s far from my favorite thing I’ve ever put on my feet, but there’s a lot to love, here.

First, is the upper. Think Nike’s Flyknit, but smoother and more cushioned. It feels fantastic. The mid- and forefoot bends with your toes and arch and feels like a second skin. It’s not super supportive, but does give a little lockdown.

The full-length Charged foam provides responsive comfort. The flexible net is thin and flexible, but feel plush.

The midsole is a dual-density foam, including UA’s signature Charged foam, which seems to have a higher rubber content, giving it great bounciness. It feels similar to Hoka’s RMAT material. You mostly notice it in the heel, but the forefoot is pretty responsive, as well (but not super cushioned). Feels good, man.

Think of the Slingflex as a budget-priced answer to the Nike LunarEpic. It’s light, versatile, and puts comfort at the top of priorities. Not to mention that it isn’t too shabby in the looks department, either (although eye of the beholder and all that). It may not be ideal for marathons, but for an all-around trainer with responsive comfort and that gets the job done, the Slingflex feels like a much more expensive shoe.

Score: 8.5/10
