As simple as it gets. It's either modern or retro modern, but a simple, large elasticated strap is making this shoe style look fresh and contemporary. There's this white, trainer style, from COS, which looks like it just stepped off 2001: A Space Odyssey. It is one part nurse, one part 60s futurism. While this pair from Jimmy Choo's pre-fall 2016 collection, which I spied at their recent press day, is dressy enough for a tuxedo or minimal enough for any business suit. Whether black or white, the future is definitely thick and elasticated!
