my woman had problems shifting with her boots on. i repositioned the shifter so it's easier for her to get her boot under it. might want to try that. it's simple to do. just pull the bolt completely out, slide the shifter off the shaft and put it back on in a position that will be more comfortable for you. might want to check your riding position too. if you wear size 14, i'd assume you're taller than most. tall people have a habit of sitting further back in the seat than they are supposed to.
