El modelo terminado en -NA como este es distribución de teclas inglés americano, si quieres la incómoda y mal diseñada distribución española busca el modelo terminado en -ES, pero que sepas que te equivocas, la americana es "la buena" y la eñe / tildes se pueden escribir con cualquier teclado de todas formas (función componer). The notch is for the cable side, which orients the top part to basically be reversed. Comfort - Huge fail. I highly recommend these tennis shoes. Very good quality, easy to install, and looks great. When I reached out they fixed it immediately and the replacement showed up the next day. Also i do like the feel of the waistband. Im 7 weeks postpartum and after having a c section I needed something easy to slide on and off but still effective. the ear pads are very nice feeling, with just the right amount of cushion. I had so many irritations without socks & blisters.
