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: "Concepts killed collaboration after collaboration in 2009. Their Blue Lobster Dunks ended up being one of the most sought-after SB releases of the year, and their Timberland collaboration was trill enough to crack Bun B's 50 Favorite Sneakers. Concepts' most interesting collaboration was the "Freedom Trail" collection with New Balance. Taking inspiration from the Boston landmark's red footpath and brown bricks, Frank the Butcher and co. put together two unique, premium models that stand out from the pack. Strangely enough, eight months after their initial release, the New Balance 875 is still hanging around eBay for $60! These are a must-cop for twice that much, so get your PayPal ready. Not your style? Head over to The Hundreds 40%-off sale and check out the Johnson mid for $41."
