I bought these after I showed up to work with two different colored shoes on (thats what I get for getting dressed in the dark).  I found these and thought they'd be perfect to keep in my laptop bag and then I'd always have an extra pair of shoes on hand!  They do run a bit small, so order a size bigger than you typically wear.  They are light weight and not very supportive - but that is not their intent.  They are not intended for long-term wear.  They are cute and simple and comfortable.  And I like the little bag they come with, as it could easily fit into a purse.
