I have problems buying sandals-I have flat feet, 8WW, and plantar fasciitis. I was told by my podiatrist that I could wear sandals but the heel should be higher than the front of the shoe. I was thrilled after trying my first pair of Sissy sandals. They solved all three problems. They have two adjustable buckles-one on the front of the shoe-which I put in the last hole to accomodate the width of my foot. The heel is high enough to accomodate my plantar fasciitis. I wore a 39 in these sandals. These sandals feel as though you are the closest to barefoot as you can get-lightweight and it feels as if your walking on a cloud. I wore these everyday on our 6 day vacation in July. They are so comfortable!!!! These are the best sandals I have ever worn!!!
