I have Chacos and I wore them hiking through Greece and my feet never hurt, however, I find them a major pain in the A to get adjusted just right and they often tighten up while I'm walking, so I'm constantly adjusting them! I have the kind with the 2 thin straps that wrap around my big toe. Because of the constant annoying adjustments and the heaviness of the sole, I really don't wear them at all anymore and I'm thinking of just getting rid of them. What time of year are you going? I would only choose sneakers for the parks but we never go in the summer so I don't usually have every day rain to deal with!
