My husband is a big guy and has VERY wide, flat feet. Buy the shoes. Wings are almost useless. Infact for ladies sandals, both the sandal can be accomodates in one compartment, but for floaters and shoes you need 2 compartment one for each half. If you have a somewhat narrow foot, they would prob be perfect. habe Ersatz für kaputten HDR 145 gebraucht. With or without the available "wings" these are barely noticeable while inserted, and dont move or come out, even during rigorous movement. Gold pair now siting in my basket. Works absolutely as advertised, seems to be made of quality material and took all of 30 seconds to install. I use it with a sound devices Mix Pre 3.
