You can find good running shoes for $60 on clearance, that is what I do. Even more likely if you don't wear a size 8.5-9 like me. Try Roadrunner Sports online, good deals there. I could but I won't pay $100 for shoes, makes me nauseated since if you do a fair amount of running they won't last even a year. I only wear them for running but 6-8 months was about as long as I could go when running 4-5 days a week. You can self test your arch and pronation.
Oh and I bought my Sidis on clearance for half price so I am just cheap, wouldn't spend $220 on cycling shoes.
