Hi OP, I was in the exact situation you are. I tried many shoes but none fitted me properly. I tried the most expensive Giro with no intention of buying. When I tried the Giro Empire, I knew that I had to pay much more than what I could afford for the perfect fit. My gaze then tumbled upon these shoes:
Sidi Wire Carbon shoes - | Primeau Velo
Perfect fit. Too expensive.
So I kept searching and decided to buy these shoes with the intention to turn them over if I didn't like them (MEC - accessible retailer in montreal):
Sidi Kaos Cycling Shoes (Men's) - Mountain Equipment Co-op. Free Shipping Available

Turned out the fit was also perfect! Liked them too much and decided to keep. You will use it for a long time. If biking is what you like, do it with the proper shoes... it is worth it!
