Los he usado principalmente para una travesía en velero. Do no buy this! There is no cushion in heel whatsoever and I very small arch support. I can tip my head to the side and slap the side of my head until I have a brain contusion, and they dont slip at all. I use them for embroidery. I would highly recommend buying this particular sandal! 7 and love it! I love the fact that these fold so it is easy to put away and the sound quality of it is good. Buena compra The only issue weve had is with expandable storage-- will recognize an SD but doesnt want to put anything on it.
