Just got mine today for a trip to Europe. I'm very disappointed as the front part of the sandal is not really adjustable. There is an elastic cover around the front with no separation and I'm afraid it will hurt my bunions. I ordered a 41 for size 10-101/2  and it just fits my foot with no room to spare. I had to adjust the ankle and heel straps so that the Velcro is showing quite a bit. The arch support is adequate. I ordered the sandals because of the rave reviews. For the price, higher than I have ever paid for sandals, they are not worth it.
