First, copyrights are only infringed by copying, so if you having copied, e.g., a flow image that you put on the straps, you cannot infringe the copyright of a flower image that you never saw and just happens to be similar. Copyrights fo not cover sturctural features of orthotic sandals/heels/flats nor do they cover the ornamental appears of sturctural features of orthotic sandals/heels/flats which are covered by patents and design patents respectively. You need to contact a patent attorney to arrange to have a search of unexpire patents and design patents to see if any of them would cover the sandals/heels/flats that you intend to sell.
