Having spent £39 on this product (including postage to France) I did expect something good, and was pleased that they look good and fit well. However, only time will tell if they are really suitable for 'athletic and outdoor' use.
I do a lot of walking in the forest, a daily walk of around 2 miles with the dogs, mostly on made paths, but I do expect this product to last at least a full year. My experience with other sandals has been very disappointing with even 'walking sandals' from Decathlon which were fairly expensive falling apart after a few months, with the uppers pulling out of the soles. I have managed to re-glue them several times but now they are shot.
An initial examination of THIS product seems to show that the uppers are very securely fixed to the sole and the sole itself is thicker. Let's hope they do what it says 'on the tin'. If they fail in a short period of time I will repost here with the results.
