San Antonio, TX (KENS/CNN) - A Texas charity is out thousands of dollars after some one-of-a-kind boots meant to raise money for kids were stolen.

Monday morning, someone broke into a vehicle and stole $6,000 worth of boots belonging to Upward Transitions in San Antonio. The non-profit uses horses to work with children with disabilities and adults with mental and physical challenges.

A San Antonio Western Wear store loaned the boots to the group to use during a fundraising gala.

"It just makes you feel crushed that you go out of your way to help kids with disabilities and someone would break into the car and someone would steal these boots that didn't even belong to Upward Transitions," said Greg White with Billy's Western Wear.

"They can call them and we can anonymously turn them in and we will happily pick them up wherever they are, would just appreciate getting them back, because our charity was responsible for them," said Amber Higgs with Upward Transitions Therapeutic Horsemanship.

The charity says the boots are worthless to whomever has them because no two are alike.

The group only used the left boot of each pair to show off during the gala.
