Are they going to be for track use? If so, don't cheap out! Get ones with armour, it's cheaper than broken bones! I like my Alpinestars Supertech R. They'll come in that size, I'm a 9.5 us and take those boots in a 41 euro (needed to go down a size on those, otherwise I take 42). Try them on; at a us 9, she's probably euro 41 in most boots, but a 40 in the Supertech R.
