A thin flat sandal on European cobblestones will have you miserable by noon. What you actually need: a sole with grip and structure underneath. The platform is what makes a sandal cobblestone-friendly. You get height without the instability of a heel, and you can actually walk in them for hours. The other thing nobody tells you: even great sandals need breaking in. Walk them around the house for at least a week before your trip. Blisters on day one can take out an entire itinerary. Which sandal style do you default to when you travel? LTKTravel
