I would have given these 5 stars if the straps worked better.  They become loose after wearing them for a short time.  But, since I got them on sale I still like the shoes and will recommend them if you are purchasing them for at least 50% off the purchase price.  The strap can be frustrating but it does not make the shoe itself loose so it's safe.  In addition, these have great arch support, they are cute and well made!  I didn't have to break them in.  They were comfortable right away.
