All you need is this. My first attempt at Chacos were the double strap. It’s my weekend scent, until I’m finished with my bottle. Genuine Dearfoams. I bought this for my Grand-daughters room to hang up her school backpack. At the end of the day though, it allows me to work out and was the cheapest one available soooo, better than 1 star 🤷🏻‍♂️ Bellissimo! They caused blisters within 20 min of wearing them and had rough spots all over the footbed. Me gusta que es fácil y rápido de instalar lo que no me gusta es que permanece el foco prendido Too perfect.
