The Perfect Fit
Of course, if you're going to buy men's shoes online, and you need the perfect fit, you'll want to actually measure your feet - or have them measured by a professional. Take those measurements, and consult the manufacturer of the shoes you want to buy, and make sure you check their return policy before purchasing.
