Touch-screen capacity and water resistance were the features that helped me in my decision to purchase! These say they are a Womens 7 but they are actually a UK 7 which is a US Womens 9. 😎 😁UPDATE: Bought another one. My first pair of chaco sandals, and I know it wont be the last. 1st thing yes the nuts and bolts will be loose but if you use tools recommended or just 2 wrenches in combination (1 for back bolt and 1 for the front at same time the bolts can be tightened) its not science. Si se enciende en derecho no se escucha el izquierdo y si intentas darle volumen, te cambia los canales del TV, o sea, no son prácticos ni operatvos para el uso rápido de la vida de un empresario. As soon as i pop open they case and pull them out theyve connected. I bought a larger size than I should have. It is easy to put on my RAV4 and I can easily carry mine & my friend’s bikes everywhere.
