For their new "all-conditions" sneaker, the ACG.07.KMTR, Nike developed a totally new entry-exit system that we're very curious to try out. Rather than laces and eyelets, the kick features a draw cord, a strap and a magnetic buckle. Here's what opening and closing the bag-like upper looks like:

"We trialed a number of closure systems, and I began thinking about how a parachute unfurls and wondered how that might operate in reverse," says Nike designer Gerald Sullivan. "Ultimately what worked best was pulling the cord through the shoe via a single hinge. This act molds the bag-like upper into form. Secondary lockdown is achieved through the magnetic buckle, which is not only low profile, but adds a distinct panache to the shoe's form."
