With only a 30-inch inseam, it takes some work to avoid toe overlap for me. I build my own frames, I've experimented with various geometries, wheel sizes, top tube vs. stem length, etc. In the end, I don't mind modest toe overlap on touring and commuting bikes. I wouldn't want toe overlap if I were riding trials or technical mountain biking, but for normal road riding, it's no big deal, I'd rather have good handling and modest overlap than zero overlap and excessive rake or a stubby stem.
