These are my favorite comfy sandals for when I have to walk a lot. I wore these walked all day for a week in Disney World and I got no blisters and my feet never hurt. The only downside is when i wore them in the pouring rain they got soaked and when they dried i felt the material had stretched and they had become too loose so this is my 2nd pair I am buying to replace the old ones. this time i won't get them wet! i wear a 9.5-10 in ladies shoes and the 10 fit perfectly.
