I am looking for some binding advice for my girlfriend. She currently has LF fusion bindings size s/m and they are really tight on her feet causing considerable pain. I bought them based on her size 6 foot but they seem a little undersized. Her foot is a little on the wide side but she buys regular sized shoes. Any advice on a good binding for her? She is a beginner...can cross the wakes and do surface spins and slides. Not really jumping yet but the pain in her feet is really keeping her from being able to ride for any length of time. Also, will most brands fit the LF boards? Are there brands that will not fit her board like Ronix? Sorry for all the questions but thanks for any help/advice!
