“Is this shoe blue or gray?” you’d be forgiven if you asked at the Kith store at Broadway and Bleecker — the royal-blue neon that spells out “Kith” tints the three display walls of this downtown sneaker studio. Even the most Instagram-addicted sneakerhead will marvel at the curated selection lining these dark-paneled walls. (Speaking of Instagram, the store maintains its own account: instagram.com/kithnyc.) You want standbys like the classic Nike Air Max 1 in the newest colors? Got those covered. Ditto your Converse, your Vans, your Timberlands, Florsheims, and Red Wings. (Or, for the steampunk with a trust fund, your Giuseppe Zanotti high-tops.) And let us not forget Kith’s own label, nor the designs founder Ronnie Fieg creates for Sebago and Doc Martens, among others. For more on the latter, see ronniefieg.com.
