I really suggest a pedicure for pregnant women. I got one at 7 months, one at 8 months, and one at 9 months. The 7 month one is really just a nice spoiling indulgence but by 9 months it really is wonderful. It's pretty hard to get to your toes and this way someone else paints them for you (so they look nice) and cuts them and everything. It sounds weird and in general I'd be uncomfortable with someone working on my feet, but by 9 months, it's totally worth it.
All the pregnancy books suggest them as a way to make yourself feel special. I can only really suggest them late in pregnancy when you're tired of trying to reach your feet :).
