Senior Airman Haylley Carlson, 28th Medical Operations Squadron physical therapy technician, presses down a foot insole onto the foot insole contrapment of the Amfit Insole Fabrication system machine at the physical therapy center on Ellsworth Air Force Base, S.D., Jan. 26, 2012. The physical therapy center is one of few Air Force base physical therapy centers that has an orthotics production machine, helping patients save money by not having to go to a separate facility and pay for foot insoles.
