Ultra Fit Jr Brannock Device was used to measure my grandson's feet accurately and we had to give away three new shoes and buy him a new pair of school shoes. It saved his feet from poor measurements at the shoe store and from probably deformed feet. The price of the device was well worth it, knowing his correct show size. Buying the device also was an education on how to properly measure a child's feet. It was easy and a very short learning curve. The service provided by the company was very professional, item came on time and securely packaged.
