Under Armour’s Speedform is a new type of shoe that’s not only not constructed in a shoe factory but is also inspired by women’s brassieres. It doesn’t have an insole and sort of feels like you’re wearing a pair of socks. Except that those socks don’t have any seams to irritate your feet and the heel cup is seamless. It’s strange to think about, so here’s a short video that shows what the hell is going on with the Speedforms from the inside out. [Under Armour]
