On days when either a man's schedule or his sense of propriety require him to wear a jacket and necktie on a commercial air carrier, shoes can be an issue. Air travel shoes must slide off and on easily, so they are easy to remove at security, don for the walk to the gate, remove again for the flight, and then put on again before landing.
Regular ASW readers may recall that I like Belgian Shoes for long flights. Those unfortunately aren't meant for the street, so another form of shoe is required before after the flight. And that's when elastic sided slip-ons come into their own.
Elastic sided slip-ons, like the pictured Edward Green Kibworths, are appropriate with either suits or odd jackets. And, unlike other slip-ons, they are made on the same lasts as an oxford, so the fitting is the same. This is a significant advantage over other casual shoe models (casuals are notoriously quirky to fit) when the buyer is not able to try on the precise shoe he wants. And with hard to find shoes like these, that's often a challenge.
By this point I'm sure someone is muttering to themself that I should just wear a pair of regular loafers. And I may, when I'm on holiday or travelling in an odd jacket. But ordinary loafers, with or without tassels, aren't formal enough to pair with most suits, and that's when I pull out the elastic sided shoes.
