This shoe is perfect for frequent travel! My feet tend to get quite cold on airplanes, so I needed a shoe that had a fleecy lining (they are not leather, and they have synthetic fleece) throughout most of the entire shoe. The insole itself is not lined, but I bought a size up, and inserted a separate fleece insole with arch support
and it worked out great! I have wide feet and it's still quite comfortable (I am 7 wide and bought size 8). They are flexible, and have a little bit of a slipper-like feel. The side zipper makes for easy-on, easy-off at the airport security check, so you don't have to fuss with the laces. You can occasionally feel the metal eyelets from the inside, but that's easily fixed by adjusting the tongue. My usual go-to airplane shoes are Uggs
, but I was looking for something a bit more streamlined that I could wear with more outfits, and travel with fewer different pairs of shoes. These do the trick. I don't recommend them for snow, but they are good chilly weather shoes, and good travel/keep-warm-on airplane shoes!
