Yuketen Chukka Sneakers in CC Cafe. Adopting a chukka silhouette, the Moc Chukka Sneaker is handcrafted in Mexico from choice cuts of full-grain leather. A deer-leather lining, leather insoles, leather tucks and steel shank all aide comfort and support. The tuck is made from 100% vegetable tanned leather which will over time take on the distinctive shape of the wearer. 'Side mckay' stitching is used to secure the ripple sole to the upper for durability.
