We will be in Sedona the second week in April and want to do a fair amount of hiking. Mind you, I'm a 65 year old woman in pretty good shape, but I don't expect to be doing really difficult hikes with much rock climbing. Will sneakers suffice? I hate, hate, HATE wearing my hiking boots on the plane from the east coast, but I will if they will enhance my hiking experiences. We are not going to the Grand Canyon on this trip.
