Candys are really quite small-feeling when it comes to riding with regular shoes. They're doable, but I would never stand up to pedal on them, nor would I ride them very far, unless I'm wearing cleated shoes.

That said, I can use any kind of cycling shoe with them (anything from superlight road shoes with a Quattro 3-hole cleat to cycling sandals with the standard CB cleat), so it's not like my shoe choice is limited.
