I will actually need to return these.  The ankle strap isn't long enough because it hits at the widest part of the ankle.  Not above or below, exactly right over the ankle.  The heel backing is a bit short, too.  If it were even a half an inch higher, they'd be great.  The straps over the toe are narrower than the base of the sole so while this works in close toed shoes, not so much for these strappy cute sandles.
