I'm of the view that most people are on bikes with cranks that are too long for them which makes bike riding more uncomfortable than it should be. Then again, how far do you ride?

Why does "without shoes" matter, if I'm not riding barefoot? I have no issue with the 170s, and I do remember feeling that the crankset on my old Raleigh Sports felt short, and that was closer to 165.
I do at least 12-13 miles a day, at least 5 days a week. Most single-day mileage is 80ish, but I've done over 160 in a weekend before.
