Red Bull left Austin without buying Vettel’s boots

Reigning world champions Red Bull left Austin without paying a bill.

Germany’s Bild newspaper reports that, prior to the US grand prix, the team pre-ordered a pair of customised, Red Bull-branded cowboy boots for Sebastian Vettel.

But Noel Escobar, the Austin-based master boot maker, told the newspaper: "We worked through the night but no one came to pick them up.

"Red Bull owes me $2,150."

Red Bull told Bild it had to cancel the order at short notice, but is happy to pay the bill.
