I bought these sandals for a 7-waterfalls trek while staying in Flic-en-Flac. They worked fine for this purpose - all straps were easily adjustable and kept the sandals glued to the feet. The trail was after the rain so it was a bit slippery and muddy, but I washed them in a washing machine and they were like new next day. The delivery was super fast - I ordered in the evening and got it next afternoon.
