PITTSBURGH — In the second week of February, a shipment from Under Armour arrived at Notre Dame. Mixed in with hats and jumpsuits and T-shirts were the boxes that Harold Swanagan, the coordinator of basketball operations, was expecting.

“I opened them, and I was like, ‘These may be the weirdest-looking shoes in the world,’ ” Swanagan said.

It was as if they had been marinated in puréed Skittles, coated with ectoplasm and then dunked in Citrus Cooler-flavored Gatorade. They come with a free pair of sunglasses and are particularly useful for when Notre Dame plays its games in subway tunnels.

The precise color of the shoes, forward Austin Torres said, is difficult to explain. He tried: “Orange-red, neon green, neon yellow and kind of a lighter, darker green.”
