T1 shoe prices here usually beat downtown Seoul by a bit.
ABC Mart in Incheon T1 sits airside among the fashion shops and runs more like a sports sneaker outlet than a tiny travel kiosk. You’ll see stacked walls of Nike, Adidas, New Balance, Asics, and Vans, plus a few Korean brands you may not spot outside Korea. Sizes skew Asian, so if you’re a US 11 or above, inventory shrinks fast and you may be picking from only one or two styles.
Footwear ranges roughly from 40,000 to 120,000 KRW, with basic slides and sandals at the low end and branded running shoes at the top. The store also stocks socks, insoles, and simple shoe-care items under about 15,000 KRW, handy if your current pair got soaked on the way to ICN or you misjudged walking distances in Seoul. T1 pricing is usually promo-driven, so check the hang tags rather than assuming the shelf layout tells you what’s on sale.
Staff in T1 generally speak enough English and Japanese to sort sizes quickly; just ask for your US or EU size and they’ll convert it to Korean millimeters on the spot. Tax-free handling is baked into the airside pricing, so you don’t need a separate VAT counter visit before boarding. Quick tip: try on both shoes and do a short walk around the central aisle, since returns after you clear T1 are basically impossible on an international ticket.
