Nike Air Zoom Pulse Doernbecher Desiree Castillo - To celebrate the Doernbecher Freestyle program, this year's six patient designers have added an Air Zoom Pulse to their individual collections. During the sessions, the designers of the Air Zoom Pulse learned about the rigors of healthcare workers' daily efforts. The work is physically and mentally demanding. The sneaker design addresses these challenges with simplicity in mind. The shoe is easy to put on and take off and just as easy to clean. The fit, cushioning and traction systems work together to protect the foot in all hospital conditions.
