Doughnut firm Krispy Kreme has created the world's first grass flip-flops to bring summer magic to the city. The al fresco flip-flops take up to three weeks to grow and each shoe is covered with over 5,000 blades of grass.

If watered regularly, the unique footwear can remain in season for over four months, meaning they are the perfect, head-turning summer-accessory for stressed-out men and women.

Krispy Kreme's Katie McDermott said: "What better way to escape the concrete jungle than by slipping on a pair of grass flip-flops and walking around in your own mobile meadow?

"We cheer people up every day with our one-of-a-kind doughnuts. But hopefully, by providing them with their own part of park life, we'll be able to bring a sense of natural calm to stressed-out workers."
