A US woman is running across the country barefoot to raise money for charity.
Rae Heim is travelling from Boston to California without any footwear to generate enough cash to buy 2,900 pairs of shoes.
The 18-year-old sprinter has got used to running barefoot after training without footwear from last year when she broke her toe, and she found bare feet more comfortable.
Despite managing more than 40 miles per day in her first leg of the journey, Rae has suffered some painful Achilles tendon, a sore knee and a twisted ankle.
