She wears a 7 street shoe, It is perfect. But I feet like I could actually go for a run in these shoes! Otherwise, this does appear to be a very solid build. I would recommend this to any runner. Not true to size . I have been wearing this brand for years and never had this issue. Like everyone else said, the only problem was the white plastic drywall ankers they give you in the package. Im obsessed. If you live next to cell tower they may be adequate for use. I like that the parts inside are very sturdily attached with velcro, so I can customize the inside of the case for whatever I want to put in it.
