back properly

The first couple of winters I had these I thought that the zips were supposed to go at the back, so that the logos were on the shin and the seam was to the rear. They pop undone slightly less readily with the zip at the front but still don't feel right. Something about the shape of my medial epicondyles makes them unsuitable to be worn with the zip to the inside; either they bite at my skin or refuse to stay fastened. These are now only rarely used now that I have some stirrupped tights but they too have to be fitted by trial and error each time they're worn.
