This is probably the most exciting feet photo you've ever seen on Instagram.
It was taken by National Geographic photographer Joe McNally from the top of the world's tallest skyscraper, the Burj Khalifa, in Dubai. McNally uploaded the photo to his Instagram account on Monday.
McNally, who said he was standing on the railing of a support structure for the building's airplane warning lights, said the photo wasn't a work assignment -- it just "seemed like fun."
"My old battered shoes climbed the worlds tallest building today," McNally wrote on Instagram. "What an amazing structure! Tweeting from 820 meters straight up!"
At 828 meters tall, the Burj Khalifa is by far the world's tallest man-made structure. At just 508 meters, the second-tallest building in the world, the Taipei 101 in Taiwan, doesn't even come close.
Here's what the Burj Khalifa looks like from a normal perspective:
