Finally, Foldable Rain Boots
The first thing most people think when they're wearing rain boots: Wow, this is probably the first time in ages that I've actually worn these, despite having complete and instantaneous access to the weather report on my phone.
So to fix the eternal problem of not having your rain boots with you when the rains rush in, a designer from Barcelona has invented the answer—foldable boots. They're called Sardines.
Designed with light and flexible rubber, the boots easily compress to a backpack size with a built-in strap so you're never without.
