I think when you first change from clipless or even cages and straps to platforms it feels very strange. You need to give it some time to get used to not being attached. I cycled almost exclusively clipless for years including on tours, then changed to cages and straps for commuting. On my most recent trip I cycled from the US to Guatemala with the cages and straps, then changed to platforms after buying new shoes that did not fit in the cages at all. I think it took me a week riding the platforms before I got used to them, and I really hated them and thought I had made a huge mistake with the change for that entire week. Then I continued on to Chile and never thought about it again. I prefer cages and straps or just plain platforms on tour because I don't want to carry a second pair of shoes, and I don't want to click around in even the most walkable of SPD shoes. I'll usually buy some kind of waterproof trail runner or low cut hiking shoe.
