This is the sandal I've been looking for. Excellent fit -- providing you order one size down from the size you usually wear.  Gives good arch support. Great around the house.  I sometimes wear a pair of thin socks with them. I normally were a size 11 US (44 Eur).  I ordered the 11 -- too large. I returned them and got the 10. The sandal is wide so with the size 10 my foot moves forward in the sandal for a perfect fit.
