This particular pair are my walking shoes which are used 2-3 hours per day (I walk my dogs 2-3 times per day). I couldve gotten away with a Large and I normally wear a Large or XL! i have humongous ankles, seriously its my least fav body part. I was able to wear them for about 4 hours before I had to switch to the sandals Id brought. These shoes really sparkle! Changing my review to 5 stars, and if my wife needs anything else for her fitness journey, I?ll be looking to Perfect Peach first! Gone are the days of knocking over spice bottles to reach the one on the elevated shelf in back or buying a duplicate spice. order down. I wasnt gone long before they were so frustrating to wear, almost falling off my feet, that I went home to put on different shoes. Sandals fit awkwardly and clumsy.
