For our holidays in Sweden with a view to 30C ° and sun, but even for that, I then had me but div. Sandals ordered to choose from and these Ecco convinced me. They are very light and they hardly notice. So we were on the first day 12 hours walking around - in fact 30 ° C - and the sandals were great. No bruises, no bubbles .... and definitely no sweaty feet, which was mentioned in other reviews yes and almost held me to buy these sandals. So for me has - despite the heat - stunk nothing :-)
Convinced but I was also that the sandal is not so chunky looks like another of the ordered sandals.
Only drawback (and this one star deduction): The velcro front is lined with fabric and so you can not completely open the sandal there but must "slip in".
Oh yes, I ordered the brown (L. Moonrock Fuego 02459). As brown I would not describe the color but. It is a bright, unexcited stone gray (the photo is the color amends).
So - who would have thought it (I do not, anyway): The sandals were also after the holiday's in shoe rack move :-)
