I am forever losing my keys and my phone and this is the perfect solution to that. My only cons are:They dont switch off if not in use. They look good for what they are. The insoles are over stuffed with a very soft, squishy material. Everyone else thought they were pretty cool, too! I also noticed that on this pair of shoes, that the black portion was larger on one shoe than on the other. I can honestly say that Wheeler pulled it off. I ordered a 2X (Which fit like a XL). Here are my personal observations for a female with a size 6. It?s smaller and thinner.
