I loved these at first on-line site, but even though I am an average shoe size (8 1/2 M) I was worried about the ankle strap. I have high arches and my feet are pretty much boney overall. These sandals are just great. If there HAD to be a negative, it would be that the toe strap is a trifle loose - but then, I have not yet spent an entire day walking around in them (as I will 3 weeks from now on tour in Italy - Yippee). I usually wear and 8 1/2, but ordered size 8 in these because they are open toe and it is only my 2nd toe that is longer (or my great toe is shorter), so with the open toe an 8 is very comfortable. My concern about the ankle strap was unfounded. I was able to fasten it to where it felt the shoe was securely on my foot and remained so as I walked around the house, but the fit was comfortable and the strap rested nicely below the ankle bone. The contour on the foot bed was friendly to my feet and the grip striations on the heel are quite sufficient for traction - but, as comfortable as they are, I would NOT go hiking in them. Also, I think a person with a wider foot might find the foot bed contour not as comfortable as it is for me. I had loved the Look of another pair of Miz Moo sandals that were the same colors as these, but had a criss-cross strap from the ankle over the arch, which could have been problematic for me, even if the look of the others did appeal a bit more. I chose comfort for my arches and am quite pleased with my choice. I would definitely buy them again
