I've worn these on trips all over the world and have been able to walk for hours and stand in museums without the pain I always felt in the past. They are easily to get on and off for airline screenings. Plus, when my feet swell in the heat, they easily adjust. These are the best shoes I've ever worn! I found them true-to-size for a medium-to-wide foot. You might need slightly smaller if your foot is narrower.
