Elon Musk may have a dogged online fanbase, but his feet? Not exactly.

The billionaire Tesla and SpaceX CEO posed barefoot in a photo with Virgin Galactic's Richard Branson on Sunday, hours before Branson's groundbreaking spaceflight 55 miles above Earth.

"Great to start the morning with a friend," Branson tweeted, accompanied by the picture of him and Musk in Branson's kitchen at what he later said was 3 a.m. 

But while Branson posted the innocent snap in anticipation of his "big day ahead"— a successful flight that initially sent Virgin Galactic's share price up 9% in early trading — it immediately found a second home on wikiFeet, the website dedicated to troves of photos of celebrities' feet.

There, 13 photos of Musk's feet have been uploaded in the last 2.5 months, and users have submitted rankings on his lower extremities.

Unfortunately for Musk, his feet have received low marks: Musk's rating is currently a 2.65 out of 5.

(Branson, meanwhile, has a respectable 3.33 rating, and Musk's chief space rival, Jeff Bezos, is besting him with a rating of 3.26.)

Still, it's unlikely Musk minds all that much. He's currently worth $180 billion, making him the world's second-richest person, and he may soon be heading to space himself: Branson told The Sunday Times in an interview that Musk put down a $10,000 deposit for a seat on a future Virgin Galactic trip.
