This was one of favorite sneakers when it first out. It features a BOA lacing system that's common with cycling shoes and snowboard boots. The basic idea is a lightweight cable system that runs over the top of the foot and is tightened by a dial on the side of the shoe. It allows for a slide in design that's super easy to get on and off. It looks great with tights and jeans and works really well as a lifestyle shoe despite the high tech nature of the upper and midsole.
