I have horrible plantar fasciitis and I wear birkenstock sandals to help. They dont have half sizes, so I went with a size 6 instead of my normal 6. At first felt like were too small but after 1-2days started will prefect fit. Look for something else. They are comfortable to wear all day and with the sports attachments are adequate for listening to music during exercise. Good fix This has a app if you want some "physical" appearance of features. like most peeps, the pain from squatting is not in the legs, or knees, its that dam bar on the back of the neck! I even tried wearing the boot all day but its awkward and yet my foot does feels great when I leave the boot on. I have two pairs of these sandals in black/black and navy.
