Our first Twit-Kicks All-Star, Andy Oliver, is also one of the biggest sneaker bargain-hunters on the net. In his weekly column, Andy helps save you money on sneakers everyone else is paying a grip for.

Andy says: “Nike's Flow caught some people off guard when they flew off shelves last weekend. If you're wishing that you had snagged a pair, this week's deal might ease your pain. When size? collaborated with Nike on a 10th anniversary pack, they clearly took inspiration from some Nike classics. This week's sneaker deal has clearly given a tip of the hat to the Flow's "emerald" colorway and colorblocking, and the result is pretty spectacular. Inspiration aside, the best part is that the Air Mariah's are now only $48 plus shipping. These are even more limited than the Flows, and about 1/6 the price, so don't sleep.”
