That is truly the hardest thing to do. These are the absolute worst socks I have ever purchased. As some reviewers noted, this sandal runs small lengthwise but is pretty generous in width. No enough volume. i am going to be upfront about this, i only used them for about 10 minutes. I havent had enough time to do a full review but so far the product is working well. Since we live in Florida, these are the cutest little sandals for her to wear. Semplicissimo e intuitivo il pairing con i vari dispositivi (l?ho testato con un iPhone 7 ,un pc Windows e uno smartphone Android che lo hanno riconosciuto in modo praticamente istantaneo) Im not taking anything away stars wise as it could very well be the shape of my ear (we are all slightly different). BT range is 33ft which I expect to be little longer as its BT 5.
