Think about where you will be going and how you're getting there. If you are traveling somewhere tropical by airplane, you'll want shoes that will keep your feet cool while still offering you protection when you go barefoot through security. If you're going by bus or car somewhere chilly, a thicker lace up that could be worn with heavy socks can keep you warm during pit stops.
Decide how much space you have in your suitcase for shoes. If you want to bring only a carry-on, it's impractical to pack more than one pair. If you are driving and have a big, empty trunk, feel free to pack the whole wardrobe.
Figure out the dress code you'll be following during your travels. If it's a business convention, you probably can't make your old sneakers your wear-everywhere shoes. If you'll be spending the whole trip on the beach, a lightweight mesh slip on might serve you from the airport terminal to the oceanside.
Choose shoes that can be removed and put back on quickly if you are traveling by air, so that you will not be overly delayed by the security check. You can find rubber-soled shoes that do not lace up if you are seeking the comfort of a sneaker-like shoe.
Shop for travel shoes at walking shoe stores focusing on comfort, durability and versatility, or seek out quality walking shoes at your favorite department store. Scala Mary Janes are a good choice for female business travelers because they have a somewhat dressy look paired with a rubber sole. Well-made loafers are a good travel shoe for men for all occasions.
