They can really "smooth out" your heels and Achilles tendons too, if you're used to real bikes (not counting fixies). Try to coast, and half a second later, the pedals hit the back of your foot with the full force of the freewheel. Guess how I know...
That was my first, and very likely my last, spin class. Horrible stuff.
