Sirotkin struggles with wrong-sized shoes
The wrong-sized shoes made for an uncomfortable debut for Sergey Sirotkin at this week's Bahrain test, but he still completed the necessary mileage in the Sauber to qualify for an FIA super license.
The 18-year-old Russian completed 76 laps of the Bahrain circuit on Tuesday, setting a best time over three seconds off the pace of Mercedes' Nico Rosberg. However, he revealed after the session that his racing boots were too small and started causing him pain in the afternoon.
"On my fast lap in the morning I made a few mistakes, so I probably lost a second," he said. "But all in all, it was a good start to the session. In the afternoon we had some difficulties with my shoes. They were too small, so it was pretty painful when I was braking.
"When we changed the shoes, it was still not the best and difficult to drive. It was not easy, but I am glad we completed the 300 kms. We know that there is a lot of potential for improvement and we should all be happy with this."
Giedo van der Garde is driving the Sauber on Wednesday.
