Nasamax fail to finish...thanks to a shoe.

Team Nasamax failed to finish the final event of the LMES season after a bizarre incident saw the bio-ethanol powered Nasamax Judd crash out of the 1000km of Spa.

Running in fourth, Romain Dumas found himself being a passenger as the car went off into the gravel trap at Pouhon, the other side of the circuit from the pits.

TV pictures showed that the car had hit the tyre wall hard and suffered extensive damage to the front, but with no action pictures the team had to wait for Dumas to return to the pits before he could provide the full story of what had happened.

And it was no regular racing accident.

Five minutes into his stint, Dumas found his right racing boot was caught on something at the side of the accelerator pedal and he could not lift off around the left hander. Braking hard with his foot stuck on the accelerator as he crossed the gravel, he managed to pull his foot away just before the car struck the tyre wall.

"At the moment I braked, a stitch at the side of my boot stayed under the throttle in some way, the throttle stayed open at 20%," he said. "I braked with my left foot, but it was too late, the car was gone. The instant the car hit the gravel, my boot freed itself, but I couldn't do anything and I hit the wall very hard. I am really pissed off, everything was going so well since the beginning of the race, and we had to pull out because of a bloody shoe."

During repairs after the off in the warm up, new bolts were used through the side of the footwell which protruded further than the old ones, and the ends may have been the cause of the chafing that frayed enough leather to get caught.

However it was too late for Dumas and the team who were left to reflect on a possible podium that had escaped for the most bizarre of reasons.
