Yeah I know that's not optimal but I don't really have the choice. I flew in another city yesterday and I didn't have enough room in my bag to take 2 pairs of shoes. But my 10k race is not really a race. I'll do it alone by myself and I think I'll have less pressure.
@pgarama is right, don't use them in the race unless you have tried them for a few dozens of km before.
Injures are always in this kind of details :-)
