I figured since I owed her I might as well give her an upgrade. I ordered a size up after reading the reviews but they still ran small. It didn?t remove a single hair off my body! This was and excellent test for these shoes they did so well I bought 3 more pairs. Easy clip on design, no sticky tape or glue used like more than a few other cases out there, and the keyring latch thing feels just as premium as the case itself. They always run big. I needed something with a little stickiness to stop that. I really like this product sturdy well built easy assembly and easy installation instructions not only can it be used for ladders but also other tie down applications money well spent I will certainly recommend this product Very comfortable, fits in line with other croc sizing. Eso sí, de segunda mano puedes encontrar a los Sony por 90 euros y a los JBL por 80.
