I have horrible huge feet for a small person (size 7 for 5ft 3) and the problem is that my toes are really, really long (it's a source of mirth in our family). I need sandals but my toes go over the edge of sandals in a 7 and even an 8. Now, I know what you're going to say, just size up and I have tried this but the problem is the length of the front of the sandal is not long enough so I have a huge gap at the back and they slip off. Am I alone in this (admittedly minor) problem? Any recommendations please?
