Vi decenas de review en youtube, en blogs, en páginas, no tienen idea la cantidad de horas que inverti, para asegurarme de esta compra. These are exactly what is advertised and they do a wonderful job. Great sandals at a decent price. I bought the first pair about 2 years ago, and in fact i still wear the first pair. I walk and/or bike regularly and it is important for me to have footwear that does not further damage my toe and feet. About 3 hours and it held up just fine. I have nerve damage that affects my feet and it makes it difficult to find comfortable shoes. I noticed many were issues with the app and/or software complaints. Gorgeous sandals really comfortable and soft. I practically live in these shoes all year round.
