Over 30,000 runners competed in the cold and rainy Boston Marathon yesterday -- with one runner making his way through the challenging course wearing flip-flops.
To be clear, these weren’t just some flip-flops off the rack. Instead, they were custom, 3D-printed flip-flops.
The runner, Chris Bellamy, actually had the sandals made by an online shoe manufacturer -- called Wiivv(WEEV) -- sending the company his exact foot measurements through a smartphone app.
Supposedly, the flip-flops are as comfortable and supportive as any athletic shoe. But after running 26 miles in them yesterday, we’ll see how Chris is feeling today. (Digital Trends)
